There are no hotels near the track and if there were some, you wouldn't want to stay there. The track isn't that close to Disney but its not that far either. The track is a short drive to Universal. Terra Verde is a 40 min drive but you will get a lot of room for a great price but it is south of the Disney in Kissimmee.
Lake Buena Vista Resort and Spa is ok, it is close to the highway, it is close Disney, it has a huge pirate ship pool, it is next to an outlet mall, it has 2 and 3 bedroom condo type nightly rentals that are reasonably priced.
I heard Sheraton Safari is ok located on Apopka Vineland Rd. Prices are around $65 and it appears clean. The hotel is a little older than the pictures make it out to be online but still a good deal and close to the highway and close to Disney.
Or you can always try Marriott Harbour Lakes, or the Blue Heron.
I hope this helps
