At Walt Disney World there are a lot of Tennis facilities to choose from. Most of the major resorts have some courts. There are both clay courts and concrete. There are also lessons available. I know you can also rent equipment at some of the resorts. The only thing to remember is that it can get really hot and humid in Florida so running around playing tennis may not be the wisest thing to plan a lot of.

You can go horseback riding out at Fort Wilderness. These are guided experiences on really tame horses through the trails of the campground. There are also hayrides depending on the season.

There are several boating options available to you at Walt Disney World. Disney's "navy" is rather large. You can choose from two person paddle boats and water sprites up to the luxurious Grand I yacht. For current pricing and restrictions you should check with guest services or the marina of your choice. You can rent boats from virtually any place at Walt Disney World that is next to a lake. Most of the resorts have boats available along with the Disney Marketplace. The best boating is on the Seven Seas Lagoon and Bay Lake (there is a water bridge that connects these two large bodies of water the surround the Magic Kingdom area). There's nothing like leaving the rush, crowds, and humid Florida air of the Magic Kingdom behind and heading out on the lake… yes the hot air is still there, but it feels so much cooler while cruising the lake.

You can also go Watersking on Bay Lake out of Fort Wilderness or the Contemporay.

There are three fireworks cruising options at Walt Disney World. One is the Magic Kingdom cruises that depart from the Magic Kingdom area resorts. All of these cruises are on pontoon boats. You basically leave the resort of your choice and you cruise around the Seven Seas Lagoon and Bay Lake for a while then you line up in front of the Magic Kingdom and watch the fireworks show. It is really a great view of the show. There are speakers on the islands in the Lagoon so you can hear the soundtrack of the show also. Then after the show you cruise around the lakes some more then head back to where you started. While you are cruising around there are refreshments and snacks for you. This is a great way to relax and see the fireworks without having to deal with the crowds of the park.

The second and third option both leave the Yacht & Beach Club and you travel to see either the fireworks show at EPCOT or the Disney Studios. Both of these cruises use Pontoon boats, or there is sometimes an option to go on the Breathless. This is an all wood speed boat that resides at the Yacht and Beach Club marina. It is really a neat boat. These cruises are extremely limited because the boat is really small. Also there was no food or drink on this cruise.

Parasailing departs from the Contemporary Resort and you go up and around Bay Lake. It is really amazing. I am not one for thrill rides (I do not go on any of the mountains or anything like that), but I really enjoyed this experience. We went first thing in the morning one day at around 6 something. It was really fun watching the sun rise over bay lake and then going up and cruising around the lake when half the world(that is Disney World) was still asleep.
