How to plan a bachelor party

Before you plan anything, get two answers from the groom. Ask directly — a general "what do you fancy?" reliably produces "whatever you lot want", which is not information.

1. Who has to be there? This is his list, not yours. It also surfaces the two people who should not be seated together, which is much better known now than at 1am on the Saturday.
2. What should this cost people? Most grooms have a firmer view than the organiser expects, and it is usually lower. He knows which of his friends are skint, and he does not want them stretched for his weekend.

Add a third if he seems ambivalent: is there anything you'd genuinely hate? People can name a dread instantly and a preference almost never.

Group size drives cost per head more than anything else you choose, so fix it first.

• 6–10 is the sweet spot. One house, one table at a restaurant, one taxi run, one conversation.
• 11–16 works but changes the shape: you will split for meals, some activities will not take the whole group, and date-finding gets materially harder.
• 17+ is an event, not a trip. Plan it as a single big night at home rather than a weekend away, or accept that half the list will not come.

Once you have a headcount, name a bracket and say what it covers. The full number, once, early — not revealed in instalments.

"Two nights in Manchester, 6–8 Feb. About £220 each: the house, Saturday's activity, and a share of Tom's costs. Trains and drinks on top. In or out by the 15th."

That message does more work than any other you will send. It lets people decline early and privately, before there is a booking depending on them.

The usual convention is that the group splits the groom's share between them. It is a convention, not a rule, and it is the single most common source of quiet resentment on a bachelor weekend — not because people object, but because nobody told them it was happening until the final bill.

Two rules make it painless:

• State it in the first message, as a line item in the headline number. "£220 each, which includes a share of Tom's costs."
• Cap it. Covering the groom's accommodation and activity is normal. Covering an open bar for him all weekend is how a £220 weekend becomes £310, and the people who quietly could not afford £220 are the ones who absorb it.

The mechanics of tracking and settling are in how to split costs on a group trip.

3–4 months out

• Two questions with the groom; build the list; collect contact details.
• Run a date poll. This is the long pole — see how to pick a date everyone can make.
• Hold the weekend at least three weeks clear of the wedding.

2–3 months out

• Fix the destination and publish the full cost.
• Book accommodation and take deposits immediately. Do not float a £900 booking on one card for two months.

1 month out

• Book the activity and the Saturday table. Both need a name against them.
• Share the outline so nobody is ambushed by a 9am start.

The week before

• One message with address, arrival times, what to bring, what is still owed.
• Chase outstanding money now. After the weekend it evaporates.
• Set up the shared photo album before you go.

A bachelor party usually spans a wider range of financial circumstances than any other trip the groom's friends take together. The same weekend can include someone with no dependants and a good salary, someone six months into a mortgage, and someone who is also paying for a suit, a wedding gift and travel to the wedding itself.

Averaging across that range is what quietly excludes people. Structure for it instead:

• Keep the core weekend as cheap as it can reasonably be, and make the expensive thing optional and separately priced. Eleven people where three skip the £70 activity is a better weekend than eight people who could all afford it.
• Offer a one-night option. Some people cannot do two nights for money or childcare reasons, and will happily do the Saturday. Say it is available, unprompted — very few people will ask.
• Never poll the group on the budget. Asking "what's everyone comfortable with?" in a group chat guarantees the answer skews high, because nobody wants to be the person who said a low number. Set the bracket yourself from the groom's steer.

Watch for creep

The published number and the number people actually spend diverge in a predictable way. A £220 weekend becomes £300 through a sequence of individually reasonable additions: a round nobody planned, a taxi instead of the walk, a second activity someone suggests on the Saturday morning.

You cannot prevent that entirely, and should not try to police it. What you can do is make it visible — keep a running total everyone can see — so that the person for whom £300 is a genuine problem finds out on Saturday afternoon while they can still opt out, rather than on Sunday when it is a debt.

• Food on the first night. Twelve people arriving hungry at 8pm with nothing booked is how the first evening gets eaten by a two-hour wait.
• A plan for the person who cannot drink. Someone will be driving, on medication, or simply not drinking. A weekend built entirely around a bar is a long weekend for them.
• Getting back. Transport to the venue is always arranged; transport home at 1am rarely is.
• The groom's phone. Somebody should have the venue details and the accommodation address other than him.
• Sunday. Checkout is usually 10am and trains are usually later. An unplanned four-hour gap with luggage is a miserable end to a good weekend.

All of the above, in time order, as a list the best man can tick: the copyable bachelor party checklist.

Most groups split the groom's share of accommodation and the main activity between them, but it is a convention rather than a rule. Whatever you decide, say it in the first message as part of the headline cost — the problem is almost never the amount, it is discovering it as an unexpected line item at the end.

Three to four months before the wedding. The planning does not take that long, but getting a date agreed across ten or more people does, and you want the weekend at least three weeks clear of the wedding itself.

Whatever the group can actually afford, which is usually lower than the organiser assumes — ask the groom, because he knows his friends' circumstances. What matters more than the number is stating it once, in full, before anyone books, so people can decline early and privately rather than late and publicly.

Six to ten. At that size one house fits everyone, a restaurant will take the booking, and decisions happen in a single conversation. Above about sixteen it stops being a trip and becomes an event — plan a single big night at home instead.
