Well we have stayed several times at the Kissimmee RV park reasonable rates great pool and dog friendly. Phone 1 407 396 6655
As for dish I have used dish on several of my RVs, and love it. I just mounted a dish playmaker on the roof of our 2004 Winnebago Brave with a 211z, I believe thatís right, but I would go with a Wally as the receiver.
I bought the playmaker from eBay for 105.00 and the mounting feet for 46.00 from winegard, installed it myself works great.
I have posts of the install if you search around.
Hope this helps. BTW Kissimmee RV park is only five miles from Disney
