DS is having his 5th birthday party at a trampoline park. You get 1 hour of trampoline then 40 mins in a room for food/cake etc. Food is a pre-packed lunch box with roll, crisps, fruit. Should I plan any party games for this time, like pass the parcel? Just don't want 26 hyper kids left to their own devices but equally don't want to over do it. Thanks
