There are much better places to stay in the Marriott family. Skip this place.
Dirty towels, pool under renovation (which no one told us about ahead of time), lots of broken down things in the room, inconsistent stories from the managers (Grace & Saul - have they even had any sort of training??). There's absolutely no level of security either. No card scan to operate elevator - seemingly anyone could walk in off the street and have access to all floors.
Renaissance Hotels come with the reputation of a certain level of service, and this place is a miss on all levels. There are so many better options within a short walking distance of the convention center. Save yourself the hassle and stay there.
