I've been to FW a few times...always found it darn near perfect....EVERYTHING is right there. Yes, it is more $ than surrounding campgrounds, but I would do the FW as a first choice. My opinion.
Uber sounds good...you can also rent a car. Enterprise advertises they bring the car to you. But I don't really know....we tow 4 down.
First off, get a map of FW (from the website), get a "loop" as close as you can to the lake. (Like, say the 600 series loop) closer, the better for an RV. Bus, boat, to Magic Kingdom. Or a series of buses from FW to, say, Downtown Disney. A bus "depot" is right there at FW. Reservations almost required. Do that on the 'net, or call the phone number. If I remember correctly, WDW has NO 1-800 numbers anywhere. But...with unlimited talk and text...it's no bother
