We did the rock climbing party for my older daughter and now my second one wanted it also.  It was such a hit with all the girls-who would typically rather have some sort of make up party!  We sent the invites out with a picture of my daughter rock climbing at the palce where the party would be held-so they had a glimpse of what would be coming- then we also had Hannah Montana Rock star supplies to maintain the rock" theme. But the really cool item was the goody bag that the kids talked about forever. I purchased velvet jewelry bags (large a handful is about $1.50-2.00) and provide literally hours of fun.  The kids keep them in the bag and can take them almost anywhere. The parents thanked me for NOT giving out candy and the kids thought they were the coolest gift ever. And it is very very difficult to lose or break them. "
