Sure, provided everyone has a ticket! The only limit is the number of seats available. We can’t add seats to a sold out event, so you can buy as many tickets as there are available.
The number of tickets available is the maximum number the venue will allow. This is related to the size of the venue and comfort of its visitors, although it may also have fire code implications.
If you're having a hard time finding an event big enough for all of you, you can always book a private event! That way you can pick the painting and the venue, and anyone you invite can attend. Go to the Group Events Page for more information.
