Party games for 10th birthday?

[Howmanysleepstilchristmas]

Dd has just announced she wants to hire somewhere and have a piñata, pass the parcel etc. Will a group of 10 year olds get bored at this type of party? Anything else I can add ? Or should I try to talk her back into her original idea of a swimming party? Budget is under £200

Can you do both? Are you having any good in a private room at the swimming pool complex?

No private room, just the poolside viewing area with fixed tables and chairs. Do you think her friends will find the hall option babyish?

You'd better get very good entertainer! Not much change from £200 either.
