What to buy for everyone?

[momb]

When I say everyone I mean 5 girls between 11 and 18?

They each get one main requested gift. Then extras like stocking presents, useful bits....and then usually there's something else one top: one year a sack of board games for us all to play together, one year tickets for a DLP minibreak together, last year for some reason we went overboard on Dr Who and ended up with a playroom full of calendars, graphic novels etc. This year my mind is blank; ideally something which unites us as a family. Minibreak is out as three of them have big exams this year so we'll all be close to home until June.

Thanks in advance (and slightly blankly)

Dates for everyone to have a turn at choosing a restaurant to have dinner in? Panto/Theatre tickets, photo shoot, spa day?

Or something like one of those pop up hot tubs for the garden? Hammock? Giant garden games? Football Table?

Trip out for afternoon tea.

Flying at Xscape, Milton Keynes (in a wind tunnel).

Walking with llamas.

Thanks for the suggestions. I think Airkix flying would be great but DH not so sure. Any other thoughts? Thanks
