The Ritz Carlton Orlando is located near Sea World, but tucked away from the busyness of Orlando. The property is extremely private and peaceful. They even have their own golf course and lake.
The Ritz Carlton Orlando has gone all out on their kids room. For a fee you can drop your kids off and go out on a date. Here they can play, watch tv, game, do arts and crafts, read, and more.
I highly recommend watching for a deal for this hotel. They run some nice packages for families. I also suggest you use their dining special that includes childcare in their kids club. It's actually cheaper than paying separately for each.
