Qual è la differenza tra I don't really care for staying in luxury hotels. e I don't really care about staying in luxury hotels. ?Sentiti libero di rispondere con un esempio.

"I don't care for" means "I don't prefer" or "I don't like". So you don't like to stay in luxury hotels. You would rather stay somewhere else.
- "I don't care for" = It does not make you happy.

"I don't care about" means "this is not important to me". So maybe you like staying in luxury hotels or maybe you hate staying in luxury hotels...but either way, it does not matter very much to you. You don't want to talk about it or think about it very much, because it is not important to you. It is not very interesting to you. Other things are much more important to you, but not this thing.
-"I don't care about" = It does not interest you, it is boring to you.
