Funny, I have a 3 year old DD and my DS just turned 13 in March! We did a big family party that was a Las Vegas theme night so we had dinner and cake and then played cards and dice. This was my son's idea so I went with it.
For his buddies party, the next weekend I rented a hotel room at the Embassay Suites and they had a sleepover. They swam (it had an indoor pool) ate pizza, we took our Wii and they hooked it up in the bedroom. I brought snacks and drinks and they had a blast. I went home with my daughter at night and my husband said they stayed up until 4a.m. My DD and I went back in the a.m. and the boys went to breakfast and swam some more. We took them all back home around noon the next day and all the boys said they had a great time and they would love to do it again. I searched online and the cost of the room was $120 which included their breakfast!!I'm sure it would have cost me that much to take them to Denny's since they can eat so much at 12 and 13 years old. good luck with your planning!
