How to pick dates for a group trip without a 50-message poll

Ask six people when they are free and you will get six replies, none of which line up. Someone has a wedding in March, someone cannot take time off before summer, and someone will tell you later. A week passes, the thread goes quiet, and the trip joins the pile of ideas that never happened.

Dates are the first real decision of a group trip, and the one that makes everything else possible. A short, structured process gets you there without a poll that drags on for weeks.

Decide how long before you decide when

People can't say whether they are free if they don't know how long you are asking for. Settle the length first, roughly:

• A weekend (two or three nights) is the easiest to fit around work and family.
• A long weekend (three or four nights) works for most trips within a few hours' travel.
• A week opens up more places but is harder to coordinate.
• Longer needs more notice and a clear sense of who can really commit.

If people disagree about length, pick the shorter one. A trip that happens is better than a longer one that doesn't, and you can always add a few days for those who can stay.

Start with what cannot move

Ask each person for their fixed dates in the period you are considering: weddings, work deadlines, school terms, existing trips, religious or family occasions. Collect these, not preferences. Fixed dates are easier to share and less open to debate than "I'd rather not".

Put them somewhere visible, whether a shared calendar, a table or a simple list, and cross out the weeks that clash. The gaps that remain are your candidate windows.

Look at the calendar, not only the dates

Some points in the year are harder than others, and they vary by place:

• School holidays push up prices and fill transport for anyone with children, and make it difficult for parents to travel at other times.
• Public holidays and festivals can close businesses or fill every room in a town. They can also be the reason to go. Check them for your destination.
• Weather seasons matter: monsoon, extreme heat, snow cover, hurricane or storm seasons. Check the climate for the place and time on a reliable source.
• Shoulder seasons, the weeks between the busy and quiet periods, often give the best balance of weather, price and space.

If you haven't chosen a destination, the dates will narrow your options. If you have, the destination will narrow your dates. Either way, fit them together early. Our article on choosing a group trip destination explains how to bring both into the decision, and the country guides, such as Japan, set out the seasons for each place.

Offer two or three options, not an open question

An open question such as "when is everyone free?" produces vague answers. A specific choice produces decisions. Once you have your candidate windows, offer two or three concrete options:

• "Friday 12 to Monday 15 June"
• "Friday 3 to Monday 6 July"
• "Friday 4 to Monday 7 September"

Ask each person to mark each one as yes, maybe or no. This takes thirty seconds to answer and gives you more information than a long reply. Add up the results, and the best option is usually clear.

If every option has a few "no" answers, think about who can't make it and why. Sometimes you can shift by a day or two. Sometimes a trip with five of six is the right trip, and the sixth joins another time. Decide in advance how many people you need for the trip to go ahead.

Set a deadline and keep to it

The most important line in your message is the date by which you need an answer. "Please reply by Sunday evening; we lock the dates on Monday" turns a debate into a task. Without a deadline, the last person to reply holds everyone else hostage.

When the deadline passes:

1. Count the replies. Choose the option with the most yes answers.
2. Treat silence as a maybe, not a no. Follow up once, privately, then proceed.
3. Announce the dates clearly, with the day of the week and the full range. Ask everyone to put them in their calendars.
4. Don't reopen it unless something big changes. People who join late can adapt.

Think about flights and arrivals

Dates for the group are not always the same as dates for each person. If people are travelling from different places, check how the days line up:

• Arrival day. Will everyone reach the place on the same day? Plan a relaxed first evening, because travellers arrive at different times.
• Departure day. Check the last-day flights and trains. A noon check-out and a late evening flight leaves a gap that someone will need to fill.
• Cheaper days. Midweek or off-peak travel is often cheaper. If flexibility exists, check a couple of alternatives before you lock in.

You don't need to book everything on the day you choose dates, but check that it is realistic. For how far ahead to book, see the general advice on timing in our group trip planning guide.

Make the first booking quickly

Dates only feel real when something is booked. As soon as the group has agreed, make the first booking, usually the place to stay, which is both the largest cost and the one that sells out. If you do this within a few days, momentum carries into the remaining arrangements.

Check the cancellation terms of whatever you book and make sure everyone knows them. Flexible bookings cost a little more but protect the group if someone's plans change. Agree in advance who covers any loss if a booking cannot be changed.

Put the dates where everyone can see them

Once the dates are chosen, record them with the trip, not in a thread. The dates, the place, and the start of the plan should sit together, so anyone can check them in seconds. Then, as you add stays, transport and ideas, the trip fills out around a fixed frame.

Keep it moving

The point of this process is to move from "we should" to a trip that is booked. Offer options, set a deadline, decide and book. A group that does that in a week or two will be on the plane while others are still discussing which weekend. When the dates are locked, the next job is to plan the trip together, so everything you decide next has a home.
