We've stayed at Mid-Bay Shores near Destin, Florida and at the Hale Koa in Oahu.
Our Mid-Bay Shores stay was a long time ago and it was called Lake Pippen at the time. Location wise, it's tough to beat if you're looking for a Gulf Coast vacation. When we stayed there it was trailers, but looking at the web-site it appears they're cabins now.
While expensive by Mustachian terms, the Hale Koa was an excellent deal for Hawaii. It's right on the beach and the grounds are gorgeous. They have a shopette on-site so you don't have to pay inflated prices if you want a snack, drink, or souvenirs. I think it was ~$140/night but the rates are rank dependent so yours may be more or less depending on your grade. Parking was $5 a night compared to $20-$25 for most hotels in the area. If you don't have a Military Star Card, sign up for one when you get there and charge everything to your room. Don't use the card until you checkout and then you'll get 10% off on your first days purchase which for us was our hotel bill and meals - saved us quite a bit.
