30th birthday ideas: party themes and trips

The ideas below cover big nights, quiet days and trips. Each one works whether a friend is planning it or you're throwing your own 30th.

1. A goodbye twenties party with art deco gold and a 1920s dress code.
2. A throwback party built around the years the birthday person was a teen.
3. A dinner for a small group, at a restaurant or around a kitchen counter.
4. A cocktail-bar night with a mocktail twin for every drink.
5. An arcade, game show or board game night.
6. A brunch, in the morning or "after dark" in the evening.
7. A backyard movie night or a glamping night under string lights.
8. An experience such as axe throwing, a wine tasting, a brewery tour or a cooking class.
9. A weekend away with a small group of friends.
10. A small or solo day that does exactly what the birthday person enjoys.

Not sure which fits? The table in the next section compares group size, cost, lead time and what to decide first.

Pick the format before the theme, because it decides the guest list, the budget and how early you need to book. A dinner or a night out suits a small group. A house party suits a crowd, and a trip needs the most notice.

The sizes and lead times are suggestions, not rules. If guests pay for themselves, make that clear when you invite them, so nobody is surprised by the bill.

Yes. Throwing your own 30th is a good way to get exactly the day you want. The only rules are to be clear about money and to share the work.

The Emily Post Institute's advice is simple. When friends take someone out for their birthday, the group splits the guest of honor's share. When you suggest a dinner out for your own birthday, offer to pay for your own meal.

Emily Post also warns that a formal invitation makes you the host, and guests will assume you're paying. So for a pay-your-own night, invite people as the one organizing a plan to meet up, not as the one giving a dinner. If you're paying for the food and the drinks, say that instead.

On InviteBird, up to five co-hosts can run the event with you on any plan, each signing in with their own account. A capacity limit closes new replies when the room is full and keeps a private waitlist of people who'd still like to come. For a house party, a bring list lets guests claim drinks or snacks as they reply.

Choose a theme the birthday person would pick, whether that's glamorous, nostalgic, cozy or competitive. Here are twelve themes for a 30th birthday party, each with a matching InviteBird design where there is one.

Found a theme? Every design on the 30th birthday invitations page can be edited before you send. Design free, pay when you send — from $9.99.

Plan one or two activities that get people talking, then leave room to eat, dance and catch up. Pick from the classics and the built-in games below.

InviteBird's birthday games run on guests' phones as they reply. For an adult birthday, Guess the birthday star, Who knows the birthday star best, Wishes & memories and a prize drawing start switched on.

Who knows the birthday star best starts with a few questions the birthday person fills in through a private link; each guest then tries to predict what they said. If you're throwing your own 30th, you answer it and find out who really knows you. You can also turn on This or that, with adult pairs such as coffee or tea.

Book the place only after the core group agrees on dates, and set the reply date before the booking deadline. That order keeps you from paying a deposit for beds nobody fills. Give guests as much notice as you can, since a trip needs time off and travel money.

1. Pick two or three possible weekends and check them with the three or four people who must be there.
2. Choose a place most guests can reach, and estimate the cost per person before anyone is invited.
3. Find the booking deadline: when the deposit is due and when it stops being refundable.
4. Set the reply date at least a week before that deadline.
5. Cap the headcount at the number of beds minus the host's own, plus-ones included, and keep a waitlist.
6. Send the invitation two to three months ahead, with the cost per person and what it covers.
7. Track each deposit and payment as it comes in, and update the cost per person as replies arrive.
8. Plan something at home for friends who can't travel, such as drinks or dessert the week after.

InviteBird's capacity limit counts each guest who says yes plus everyone they bring. The person who owns the event isn't on its guest list, so a cabin that sleeps 10 gets a limit of 9. Co-hosts are on the guest list, so their replies count. The party budget planner keeps planned and actual costs, deposits and the cost per person, and it's included on every plan.

If friends would rather chip in toward the birthday person's share than bring presents, Gifts & funds can show your own Venmo, PayPal, Cash App or Zelle on the reply screen. The gifts unlock is $14.99 per event, and InviteBird never handles the money. The two largest plans, Open Sky and Horizon, already include it.

Let the format set the menu. A dinner calls for shared plates, a house party for a build-your-own bar and a game night for snacks people can eat with one hand. Each drink in the table below has an alcohol-free twin, so guests who don't drink still get something special. When alcohol is on the menu, settle how each guest gets home before the first drink is poured: a friend who stays sober, a taxi or a couch to sleep on.

The cake doesn't have to be a cake. A tower of donuts, a giant cookie with candles or a cheesecake works just as well. Ask about allergies when guests reply, and label the food on the table.

Pick one color palette and repeat it on the invitation, the table and the cake. A few strong pieces, such as a balloon garland, a photo wall and candles, do more than many small ones.

For a throwback theme, decorate around the years the birthday person actually remembers. The table below does the math.

Use the years from 13 to 21 for the playlist and the photo wall. Ask family for baby photos from the birth year, and friends for pictures from high school and the first job.

Plan around what the birthday person enjoys, not around "for her" or "for him" lists. Start with how they like to spend a day off.

If you still aren't sure, ask their closest friend or partner which of two plans they'd pick. Two choices are easier than ten.

Only if the birthday person would enjoy it: a surprise suits someone who loves attention and has said so before. If you go ahead, start four to six weeks out, name one person to bring them at the right time and ask guests to arrive at least 30 minutes early. The milestone birthday party checklist has the full surprise plan.

For a party, 30th birthday invitations should go out three to four weeks ahead; for a trip, two to three months ahead. Make replies due about seven days before the party, or before the booking deadline for a trip.

The Emily Post Institute matches notice to the occasion. Its chart allows a casual party anything from same-day notice to 14 days, cocktails between one and four weeks, and a formal sit-down dinner between three and six. It adds that bigger or more important events deserve more lead time. A milestone birthday counts as important, so aim for the early end even for a small dinner.

Decide on plus-ones before you send. InviteBird plans are priced by the people attending, plus-ones included, starting at $9.99 for up to 25 people. Invitations go by email, text (US and Canada) or a link, and you can schedule them to send on a set day.

The adult birthday invitation wording guide has full sample invitations, from a dinner to a black-tie party.

A cabin weekend shows how the dates, the replies and the deposit fit together. Here is one plan from first message to final count.
