We stayed at the treehouses last year in August. I rented an
ECV but did not get a handicap accessible treehouse. I did request a treehouse near the walking path to the rest of the Saratoga resort. Our treehouse was one of 2 that were the closest to the walkway to the main resort area. We never used the internal treehouse buses, we always just walked over to a regular bus stop. I forget which one it was, but it worked out great for us because it was the first stop for the buses coming in to the resort so with me on my
scooter I had a better chance of not having an already full bus pull up.
We were a brief walk to the treehouse pool. It is nothing spectacular, just a plain ol' non-themed rectangular pool and a hot tub. But it was also very un-used. I had 4 teen-age boys and they could go there and horse around without disturbing anybody or watching out for little ones. Hubby walked up every night and sat in the hot tub for awhile. It was almost like our own private pool. A few times other people would come as we were leaving, or would be leaving when we would get there. But I think only once were we there for any length of time with any other families.
As for my ECV - I took a lawn mower tarp cover and an outdoor extension cord and parked it under the treehouse and charged it down there each night and would cover it. It was well protected under there and probably didn't really need the cover but the cover I got was a dark green, so it also helped it to camoflauge it a little. of course I had the key with my so it wouldn't have done anybody any good to try to take it, but still.....
We enjoyed our stay at the Treehouse, did not experience any mosquitos or other bugs or critters.
