We travel with liquid prescription medication which must be refrigerated. Our favorite chain of hotels has recently started charging $10/night extra for an in-room fridge, which formerly had been free. Considering how many nights/year we spend (or used to spend...) in this chain, I'm thinking of contacting their HQ and phrasing my question on fridge charges as an ADA accommodation, i.e. getting the charge waived.

Do you think that is reasonable?
