We rent a boat each trip. Its very relaxing, but you are watched closely by patrolling lifeguards. At POR you can go right the way up to Downtown Disney, though their is a lot of traffic there and you need to be careful passing under the bridges, with the oncoming ferrys. I prefer renting a pontoon to watermice as it gets really hot in the watermice, and the pontoons have a shelter and you dont have to wear a lifejacket unless your under 16 I think. The pontoons go as fast as the watermice.
