looking at possibly doing the DVC next time we go to WDW but I hav loads of questions so here we go:
whats the "nicest" DVC?
There's a reason to say that about all of them! I think SSR is the most elegant, but they all have their plusses that depend on how you define 'nice.'
No kids, can't say. Again, they all have their angles. As a kid, I'd have loved VWL over all the others. I don't like clowns, so BWV doesn't do it for me, but I'd love the Boardwalk as a kid. Same for BCV.
BCV and BWV win here, with a close second to VWL for its boat ride to MK.
can you do DDP if staying at DVC?
As others have said, yes.
do you get the resort benefits such as pool, housekeeping, room service etc..
You get access to the same resort amenities, but not the member perks. Some resorts have room service, some don't. I think you have to be attached to a hotel to get that (like VWL, BWV, and BCV). AKV should be in that list, too.
Housekeeping is different if staying on points than staying on cash. You get limited service (Trash and Towel on day 4, full on day 8) with points. If you pay cash to WDW for the room, you get full housekeeping. You can order housekeeping for individual days for a per-day charge, if you like.
You won't get perks like pool hopping, free dvd rentals, and free valet, though renters have reported getting them in the past. I believe they are now asking for the blue DVC member card instead of letting the room key indicate your status.
