Just the husband and I, I think we could stay forever. We never tire of watching the sun rise.
With kids, their isn't that much to do and a 2 1/2 hour drive to WDW is out of the questions.
The longest we have stayed is 5 nights. We prefer to stay when we have enough points to accomodate a couple of friends from home. We have 3 inn rooms reserved for next July.
