Hi coisty, we stayed in one of the Thomson silver villas last September and it was lovely! The villa was located at Old Bridge Circle in Kissimee, about a 20 minute drive from the Disney parks.
We had an excellent time and were more than happy with the villa itself, the kids loved the pool and were in there every day. I can upload a few pics of our villa/pool for you to take a look at if you are interested.
I don't think you will be dissapointed.
