It became an ADA requirement in 2014 that public pools have pool lifts. A lot of public pools like hotels opted for portable pool lifts. Apparently those do not meet ADA guidelines. Some pool owners are switching to permanent mounted lifts. You may find a slightly used portable pool lift. Check with your vendor. I have all this info second hand so it may not be right.
BTW, I use a ski vest in the pool. I generally need help getting it on. I have dual handrails in my pool. With help from my wife with a few stairs I can get in/out without a lift...for now.
