We'll be staying at the POR and I understand that we can rent Searacers there and travel the river to the lake area near Downtown Disney and that the boats have a less powerful engine than the ones you can rent from resorts in the 7 Seas Lagoon area. Has anyone rented from the POR and is it worth it? I'm wondering if my husband and son (riding together) would enjoy the slower boats or if the time and effort to go rent at one of the other resorts would be worth it...... your thoughts?
