We will be staying offsite for our Disney trip this March. However, I would like to stay on site the next time we go and would like to try out one or two of the pool areas at the resorts to help us decide where to stay next time. Are you allowed to use the pool facilities if you're not staying at the resort? We'll have a rental car, so should we just drive to the resort and walk right in to the pool area? Or can we buy a pass or something to the pool area for the day? Which would be the "coolest" pool areas to try for 5 and 6 year old boys? I was think maybe the Caribbean Beach Resort?
