We like Bldg. 5. It is in the center of the resort. There are no parking lot views from this building. It is close to the river, pool, food court, bus stop, etc. A very nice location.
The only con is if you have a pool room and there are teenagers out there late at night...sometimes you can hear them. But, we simply asked the front desk if they could send security by (11pm) and remind them we had kids sleeping. The noise went away and all was fine.
