What an interesting forum thread.
If someone came at me with an inordinate amount of 'requests' (oftentimes more like demands) I would tell them flat out, my place is not for them and that no, I am not going to turn my place upside down and use all kinds of foreign products (not even available in Belize) just to accommodate them. Maybe everything has to be 'equal' within US shores (where I do not live any longer), but not in many places outside of it where pragmatism still prevails.
Having said that, I just had the most cool experience with a truly handicap guest. She booked and when we were communicating on physical pickup at her hotel, she warns me 'I hope the wheelchair doesn't scare you'. Huh? Sure enough she has been in a wheelchair all her life, but travels all over and takes her chances on the good will of mankind. I told her, if you got the guts to travel all over and does everything to fit and not demand special treatment you are my kind of person. I put her with my best guide. We dragged her everywhere: snorkeling (used propelling sea-scooters), up & down ruins (power chair), got to be with sharks and turtles (new small boat with glass bottom), etc etc. A thrill a minute, the whole week she and company had a blessed ball, with so much laughter they resembled the gregarious Jamaican Bobsled Team. She was really a real treat to host.
To me, attitude is everything.
