So my son and I went to a next door neighbors birthday party, he was turning 2. They had the Fun Bus there. It is school bus that has been transformed into a an indoor playground. They had 1 hour to play around in the bus. During this time they had alot of tumbling activities, including rings, balance beam, tire swing, summer salts down, a swinging bar, basket ball hoop, singing songs and so forth. The bus was air conditioned and played children's music the whole time. the kid's had a blast and the 2 women that were running it were awesome with all the kids. It was a fabulous time for the kids and at the end they got to go down a slide on the back of the bus. It is a great idea for about 5 or 4 and under. Older than that they kids are too big.
