I would suggest that you request near the pool at the south bus stop. Excellent area and the path is really not that far from that location. Sure beats walking a long way in the rain from the bus stop. We were there last summer and I wouldn't want to be located anywhere else at the treehouses.
I made that same request when I booked a THV for last June's trip. We were right near the path and bus stop, as well as the pool. Great location and exactly what I requested. We walked to the Grandstand and/or the Springs daily, only using the THV internal bus system once. Hope you get your request
I stayed in unit 7032 and it was an excellent location. It was next to the path and the bus stop and a short walk to the pool. See if you can get that unit or one close to it.
I was worried that it would be noisy there, but I didn't hear a thing once I was inside the unit. We loved staying there - have fun!
We requested South end, canal view and were placed in 7030, right next to the path, close to the pool, and not far from the boat dock. Excellent location. Good luck with your request, but my hunch is you're going to love the treehouses. We did!
