What would become less luxurious when accommodating son? (5)

Ross

I believe the answer is:

hotel

But I can't explain it at all!

(Other definitions for hotel that I've seen before include "Overnight accommodation" , "Letter transmitted" , "Where one may stay" , "guest house for a song before 8 [STATE] ..." , "Oh, let it take guests" .)
