I was going to suggest New Beginnings retreat too if you are having the surgery with Dr Garramone.
I am completely stealth, but happen to be friends with another guy who has gone through transition. He saved up to go to America to have his surgery with Garramone (we are from England) and asked me to go with him. We stayed at New beginnings and they genuinely are great there. They always have people there, and its only open to guys having surgery, so everyones in the same boat and its very social if you want to join in, but youre also given your space and privacy.
Plus, they pick you up and drop you off at the airport/your pre op/your surgery etc.
Also, if you just explain at the airport that you have had surgery, then the workers are usually happy to help carry your luggage etc. On the way back, my friend used the airport wheelchairs, this helped loads, a worker pushed him (I handled the suitcases) and since he was in a wheelchair, we skipped all the queues!
If it helps, I had my 2nd stage of lower surgery, which was pretty hefty and taxing on the body, much more than top surgery, and I did that by myself. Part of the whole experience included me dealing with the hustle of busy London! So coping with being recently post op, is not impossible
