We love SVR so much, we bought two annual floating weeks (resale, of course!) after our first stay. The resort is so awesome, it makes staying anywhere else mighty hard (we are in Orlando right now, staying at Wyndham Cypress Palms for a week before we check into Sheraton Vistana Resort this Friday, and are regularly comparing how WCP doesn't quite stack up to our beloved SVR).
It's the perfect place for a couple. So many adult-focused activities in addition to all the special events for kids. The amenities are wonderful (and varied), the pools are large and lovely, the villas are spacious and well-appointed, parking and internet are both free, and you can easily enjoy a vacation there without ever leaving the resort.
I don't think you'll be disappointed. The link that Klayfish has linked to is a perfect place to learn all about our favourite resort in Orlando!
