Just got back from a 2 week trip and did the DVC tour of both VGF and RIV. We have never been at either resort. Grand Floridian was FAR and away our favorite of the two. Better location/transportation options and way more dining/shopping options. We also liked the "vibe," lobby and grounds much more. We would be one of those families who would buy in only wanting to use the 1 or 2 bedrooms, though, not the new Resort Studios unless we were desperate. So, current owners who are concerned that the added Resort Studios will make the deluxe and multi-bedroom suites more scarce are likely correct. We'd be buying in with no intention of ever booking the resort studios.
I'm glad we toured them both, as going into it I was sure I would like RIV better. However, the rooms and grounds didn't "wow" us like the refurbished rooms at GFV. We rode the Skyliner and were surprised how often it stopped and how long the short trip to Epcot took.
Now to convince my husband to jump on board by the time sales open to the public. We would be new owners, so a few weeks to decide yet.
