I made my reservation online and am not sure how to request a site. We just bought our 5er and will be over 60' long. This will be our second trip with it (the beginning of our full timing, work-on-the-road life) and I'd prefer an easy in/out site. We've had other trailers, but nothing quite this long. I don't remember seeing a way to request a site prior to check in. We'll be moving here from a BLT GV, so we probably won't be there at o'dark thirty to check in, although we could ferry over and check out sites before we go to pick the trailer up from the other campground where we're leaving it while at BLT. Suggestions? We're DVC, so are much more familiar with navigating THAT system!
There is no way to request a specfic site. You can request loop and as bama ed stated if you are a there early enough, plead for a site you like. Sites are assigned about a week out, and can possibly be changed depending on what is available with campground turn over.
I suggest finding a big parking lot, a couple milk jugs and practice backing up, both to the drivers side and passenger side. Fort sites are located on both sides, and you never know.
There are no easy in/out sites at the Fort, it was designed years ago, before everyone started towing behemoths. There are some easier sites, but no guarantee that one would be open. Check out the site, the earlier in the day the better, see if it is ok, and if not you can ask to be switched, and they will try to get you a more suitable site.
First thing I do is have them note the size of my Fiver and rig on my reservation, so that they know I am coming in with 43ft, 60ft overall and 6 slides. This way Disney can plan accordingly that week out when placing campers in the system.
The other unknown to getting in to one's site is how others are parked. Sometimes people on other sites are not so considerate when parking, either cars or golf carts. This could also complicate the backing in process.
Above all, go slow, take your time, get out and look if need be. It is not a race, it is not a timed event. Once saw a camper take an hour and a half to back his new Fiver in to a camping spot.
But he was learning and was determined that he was going to make it work. The site was fine, his skill was lacking as this was also his first trailer I believe.
So again the best advice and I am still doing the same, practice, practice, practice.
And I have been backing trailers since learning to back a 40ft horse trailer at the age of 15.
