What is the purpose of your trip? There are several lower- to moderate-price chain hotels I found in AAA book that have loyalty programs(Comfort Inn, Best Western Ambassador Inn, Ramada Limited). I am not familiar with these specific point-earning properties but have stayed about five times at a place that is very casual in atmosphere, pricey, has no miles or point program, but has a huge -- no, let's say gigantic indoor and outdoor waterpark area. Conventions are held there, but there are many families. I have also looked at a couple of places with indoor or outdoor water facilities. One hotel has opened in the past year and a half or so and has recently opened outdoor facilities. One resort has a golf course adjoining the hotel. Hotel room supply used to be short, but that is quickly changing. Many of the resorts have floor plans posted on their websites. don't be surprised if hotels require two night minimum bookings during peak times, so if you don't plan on staying two nights try booking very close to your arrival date (a day or two before) and the minimum stay requirement may be lifted if your room type is available.
