The wife and I are heading to the Poly Villas in June for our 10th wedding anniversary, and first trip without our kids! We just booked it in January because we had some points free up, and we pretty much got hooked on Disney when we stayed at Poly Resort. That trip lead us to looking into
DVC. O'Hana dinner is awesome and worth the trouble to get.
Any monorail resort is a great place to start because you can hop between GF, Contemporary, and Poly with all the different restaurants and lounges. We are going to the Cali Grill, O'Hana, Kona Cafe, and Narcoossee's.
Good Luck.
