We got daily full maid service by hanging the door sign.
The room was clean except for the dirty cover of a soda cup next to the built in window seat. Our room had a king bed with fluffy soft pillows (too soft but tolerable) and a living room with a giant 9 foot sofa, a spotlight, flat screen TV, 2 giant picture windows, closet with enough hangers, huge bathroom with shower, spa tub, 2 sinks, & 4 large bath towels (without us asking for 4 towels, TY MGM Housekeeping). We were on the 24th floor with an amazing view of the colorful LV strip.
After checking in online to avoid the long lines, we stayed at a 693 sq ft Tower Spa Suite in mid Dec as part of our MLife Rewards.
Some may have a negative review of this place but it all depends on which room you book.
