If I could give no stars I would. Room service and front desk are literally unavailable at any time. I called repeatedly over 3 hours and no one ever answered. I left no less than 5 VMs, which were never returned. The only way to gt food ddelivered to my room was to physically waalk down to the restaurant, place an order and then aask for it to be delivered to my room. And then, they got the room number wrong. When I went down to the front desk to speak to a manager, I was told there was nothing she could do about her staff not answering the phone, She said they were very busy. Meanwhile, there were two people waiting to get checked in that were furious. They said they had been waiting 45 minutes. As someone who has a heart condition/arrhythmia, not being able to reach the front desk in an emergency or to ask for help (especially at altitude) is incredibly unsafe, not to mention a huge liability for Marriott. Imagine if I (or someone else) needed help and couldn't get a hold of anyone to call for an ambulance. Luckily, this didn't happen. I would never recommend this hotel to anyone. In fact, I called Marriott Bonvoy and opened a case. Hoping they do something about the hotel staff and manager.
