I think perhaps some of the trepidation is a little overdone.
The way I looked at it, the aft elevators gave direct access to Cabanas. That was a PLUS. So when I wanted to go to Cabanas from my Midships cabin, I didn't go to the Midships elevator (where I would have to walk past the whole pool area, much more difficult than walking through Cabanas to get to the pool, IMO), I went to the Aft elevator and was directly at the back of Cabanas, where the line was usually shorter than the front of Cabanas, BTW.
Thus, the reverse is true, if your cabin is aft, but you want to go to the pool, you can go to the Midship elevator on your floor and come up by the pool if you don't wish to walk through Cabanas.
