Has anyone done this and if so please can I crib it!? DS's birthday tomorrow and party in garden on Sat. We have a trampoline and climbing frame and have bought a paddling pool and water slide. Also got bouncy castle coming but.....rain is expected at 1pm just as party ends. Doing a BBQ so could leave that til later and then move indoors if needs be. The children have done pirate things at school this term so a treasure hunt would be fun. Many thanks
