all 3 building are open now - the lake views can be noisy and the first floor views are blocked by the bungalows - so would go for a third floor view - Polyn does have elevators - but the stairs are much more convenient. the elevator is in the middle - while the stairs are on either end.
that say my favorite of the
dvc resorts is BLT - LOVE, LOVE walking to the MK (the monorail back is okay - but there are no hills walking to and from BLT - so that is definitely the easier route for me)
