I would need more details. Was the concierge desk not open during the hours it was listed as being open? Or did you just not like the hours?

Service was rude - once? twice? repeatedly? hourly? What was "lukewarm"? Dear sir, sorry 'bout that, The Manager?

I'm also not a big fan of "what should I get" and "what's this problem worth" discussions. Writing back that "I want more points" seems crass. Maybe forward the note to Marriott Corp Customer Service. Personally, I'd be more focused on how to fix than WIIFM.
