Of the ones I have stayed at:
1) AKV--I love how I feel transported to Africa. I love the animals, the music, the dark decor, the exotic atmosphere.
2) HHI--I love the marsh and the wildlife. I love the old oaks draped with Spanish moss. I love the low-country cooking on the island. I love relaxing on the huge balconies. I'll be there in 15 days and can't wait!!!
3) OKW--The condo feel is similar to HHI so I think that's why I love it. It's very different from AKV though. Very bright and airy. But I like a beach feel too every once in a while.
Now I have not stayed at BLT, BCV, VGC, VB, and Aulani. Maybe one day.
