As erionm said, pool hopping PRIVILEGES are only expended to
DVC Members, NOT renters.
Don't mean to sound snarky but it really twists me when people are encouraged to circumvent the rules. One of the reasons we (members) lose perks is due to abuse of the system.
OKW has a great pool. Enjoy it!
As for location, we like different areas for different reasons so I wouldn't get stuck on one particular. And don't let people freak you out about the size of the resort. All buses stop at Hospitality House on their way out of the resort so you can get on any bus to get you to the main pool area.
