After booking our suite in Oct '24 and confirming it (and the availability of a kitchen to cook for our food-allergy kid) in Dec. '25, we received an EMAIL on the MORNING OF our check-in (May 23) that they had double-booked (blamed Expedia) and could not give us that suite. Thankfully, I saw the email and called them. They offered us an acceptable alternative (two rooms, but nearby and with a full kitchen), which we took, only to receive a call a few hours later (30 minutes before we were leaving on the 7.5 hour drive to D.C.) This time they told us that their "sales department" wouldn't give us those accommodations either, and offered us two separate rooms without the kitchen space/amenities needed, and assured me that they were doing us a "favor" by moving things around so that we could stay there in spite of the error. By the grace of God we found another hotel with the proper amenities and enough beds, but that was difficult on the Friday of Memorial Day weekend. Their blunder could've really ruined a long-planned trip. I then couldn't get them to confirm the refund (they kept stating that it was a busy Friday and they didn't have time to deal with that right then, but it would get taken care of), so I had to call Expedia and they made that happen for us. I wouldn't trust this hotel to be organized enough to guarantee you a room (even when it's been paid for months ahead AND confirmed on the phone with Marriott). It was an absolute mess.
