Found the following on All ears net.....no mention of towels so my guess would be that they don't have them at the pool......
Are there pools and where are they located?
There are two heated outdoor swimming pools available for FW resort guests only. The main pool is located near the Meadow Trading Post in the center of the campground and the second smaller pool is located with the Wilderness Cabins, between loops 2500 and 2700, which is more near the resort entrance. Lounge chairs and tables are provided. There is a shallow kiddie pool at the main pool. Also, child-sized life vests are available at the pools free of charge. The pools are open 24 hours, but the lifeguard hours vary seasonally.
