Meh -
No daily housekeeping is a plus (except for the housekeeping staff that likely have lost jobs). Daily housekeeping is a waste.
No room service and no in room minibars is not a loss at all. They were just ways to waste money.
Lounges in the US are basically pointless anyway - last one I was in made people pay for drinks
So really the only thing in this I'm slightly bothered by is the potential of some in-hotel restaurants closing.
