Just organising dd's 3rd party so thought I'd check opinion here first.
Party will be at zoo. Price includes 10 children and 10 adults. Additional adults can come for an extra fiver. After the party everyone can spend the rest of the day at the zoo if they wish.
So dh thinks that some people may want to make a day of it and have 2 parents attend for each child. WIBU to tell people that both parents are welcome but to ask them to pay the additional fiver themselves for the second adult?
