Generally speaking, a Group Booking is for any party of 10 or more tickets.
There are exceptions to this rule though, some shows may offer Groups for as little as 6 tickets and other shows may be exempt from group bookings entirely.
If you have a specific show in mind that you would like to book for please Submit A Request or give us a call on 0207 206 1174 and we'll let you know if that show is eligible.
