Thanks for the trip report!
Getting concerned that Marriott seems to be going to no desk situation at full-service properties. If you get a moment & if you feel strongly enough about it, please mention this is NOT good for biz travelers.
Can you ask what the situation is for the M Lounge on the weekends? Most seem to be open 24/7, but only do brekkie and evening offerings Sun night-Thursday night & brekkie only on Sat/Sun mornings, & no evening food options on Fri/Sat nights.
Also, any confirmation if the free drinks are for opening timeframe or if they think it will continue. Tres weird no coffee or tea out after noon.
Did they offer you the PAG? (500 pts or $10FB coupon).
Cheers.
