Hi Sandra!
The great news is that you can swim in all the pools that are located at the Resort that you are staying at! Unfortunately you are not allowed to use pool in the Resorts that you are not staying at and some pools, such as Stormalong Bay at the Beach Club, require you to show your room key and get a wristband to be able to even enter the pool area.
Most of the Walt Disney World Resorts have at least two pools and some have more pools to choose from! Many of the Resort pools are themed as well. Two of my favorite Resort pools are; Stormalong Bay at the Beach Club Resort and the Volcano Pool at the Polynesian Resort. Many people often choose a Resort to stay at according what kind of pools are there. Click

Here is some information on the pools at Disney's Saratoga Springs Resort & Spa from www.disneyparks.com:
High Rock Spring Pool is the feature pool at Disney's Saratoga Springs Resort & Spa. Located near The Carriage House lobby and reception area, the 161,000 gallon, heated High Rock Spring Pool has a unique waterslide. Beautiful rockwork with cascading water surround the zero-entry pool, meaning there are no stairs into the water; the entry into the pool is gradual. The play area offers kids the chance to interact with a Donald Duck water sculpture. Nearby are 2 whirlpool hot tubs.
Disney-trained lifeguards are on duty during High Rock Spring Pool hours. Additional pools are found in The Grandstand, The Paddock and Congress Park sections of the Resort.
I hope you have a magical time on your next trip to Walt Disney World!
Keep Dreaming Big!
