Others have given you good advise but I'd like to ask why you want to rent one? I'll preface this by saying we own a fifth wheel and have stayed at the Fort and will be there again the 1st week of December this year so love the Fort and our RV. Having gotten that out of the way, have you ever stayed in a RV? Is price the reason? Is it you just want to stay at the Fort? I don't know how much it costs to rent one but I'm thinking once you pay the rental cost, the cost for the site and possibly rent a golf cart, you could probably stay in a moderate resort for the same price. The Fort is fun and definitely has a vibe totally different than any of the resorts but it's huge and if you plan on visiting any of the parks other than MK, you have to take the buses. So you either rent a golf cart and park it at the bus depot or you take the internal buses to the bus depot to get to any of the parks. Like I said, we love our RV and love the Fort but neither are for everyone.
