I think I already know the answer to this one but I'm clutching desperately at straws... there's a great venue that I could hire for DD1's birthday party but they will only offer exclusive use outside normal opening hours. this translates as either 5pm-7pm on weeknights (not Fridays) or 6pm-8pm weekends. I think that's too late but I really want the party there! It must be exclusive use as otherwise the numbers mean it would be more expensive to pay per head than the private hire charge, plus it's a popular place and DD1 is very shy and is unlikely to join in if there are crowds of other older kids there that she doesn't know. This place is popular with older kids as it has one of those huge high slides that you use a mat for and also a climbing wall.
So, how unpopular would I be in the school playground if I arrange a party at that hour...? if it helps, siblings would be welcome to come along although the sit-down party food can only cater for a limited number due to the size of the room so they wouldn't be able to have the party tea.
