I don't believe a water view makes much of a difference in a value resort.
Here is what I tell Pop Century questioners:
If you have a car, request the 50s. Their parking lot is apparently bigger and less crowded although I personally haven't seen it.
If you are taking Disney transportation, request the 70s or 80s. They are closer to the bus stops. Their closest parking lot, however, is too small and fills up soon after the parks close.
The 60s is a central location and are sold as "preferred rooms" - for an extra $10 a night you can be guaranteed a room close to the main building and pool.
