I've stayed at that new Westin (Lagunamar) and it is really nice. It's directly across the street from La Isla shopping center and it has a bus stop in front.
As far as the hotel goes, I was there in May and even with the humidity, it was still gorgeous. They have wonderful pools, a nice fitness club, spacious rooms with kitchenetts (as mentioned above) and washer/ dryers. They only have 2 room setups, one being a king bed, the other a queen with a pull out couch, but they do have joining rooms. The hallways are outdoors (no A/C) but the rooms a wonderful A/C.
They also seem to have high Cash & Points availability (I believe its 4,000 points & $60)
I would highly recommend it.
