Hi,
I don have a specific building number for you but we like to stay in the grandstand section when we go. I has a great quiet pool with a bar and drink station and a water spray section for the kids. There is also a lighted path that leads to the main building where the resturaunts are. Its about a five minute walk tops. Lastly, its the first bus stop on the route.....a big plus for us.
Hope your friends have fun!
