I've stayed at Marriott's Ocean Watch, but I didn't use DVC points to do it, so I don't know how hard or easy it would be to get thru II. It is, however, one terrific resort!
One caveat though: there will be construction for some time to come. A total of 5 buildings are planned. 2 are open. A third is significantly under way. This building includes a parking ramp, check-in facilities, and many other amenities. Once this building is completed, I think the majority of the construction inconveniences will be over. I don't think construction of the last 2 buildings will have much of a negative effect on staying there.
