AITA for refusing to share my accessible hotel room with an older relative?

For a family reunion, I booked the only accessible hotel room because I use a cane and need the walk-in shower. My seventy-eight-year-old aunt booked a standard room upstairs.

The elevator failed on arrival day. Staff offered to move my aunt into my ground-floor room if I switched upstairs. I refused.

My aunt can climb stairs slowly but found the trip painful. She missed breakfast the next morning rather than come down twice. Relatives said I was younger and could manage the stairs with help.

I said the shower and handrails were why I reserved that room months earlier. The hotel’s failure did not make my access need optional.

There was another possibility: sharing the room, which had two beds. I rejected it because I had paid for privacy and my aunt snores. She ended up sleeping in a relative’s room on the ground floor while that relative took hers upstairs.

I was right not to surrender the accessible room. I am less sure that refusing to share it for one night protected access rather than comfort.
