Don't expect YOUR confirmed room to be held!
Being Platinum members, we have stayed at Marriott hotels for many years! This time was terrible! We had car problems so I called at apx 3:30 p.m. and told them we'd be late...possibly after midnight. The woman with an accent told us that this was not a problem, our room would be waiting. 
We arrived at 2:00 a.m. and they greeted us, sent us to our rooms...and we found it was a one bed room...our reservation specifically showed a confirmation of a double room! There were three of us...where were we to sleep? I went back to the desk, he told us that they couldn't help if we were late...the hotel was full so they HAD to give our room away! We were exhausted and it took until 3:30 a.m. to get a small cot, for our 6'4" son, to sleep on! 
I asked for a manager...none on duty. We were told to get a better room for our next night, again one that was booked in advance...that we would have to be in the lobby at 6:30 a.m. with our luggage, to check out of that room to another. 
Exhausted with only 2 hours of sleep, we showed up at the desk...still no manager! We were told to leave our luggage and it would be placed in our new room as soon as it was available. 
At noon I called and was told our luggage was in our room. At 4 we returned, expecting to get in our rooms to get ready for dinner. Our luggage was still sitting there. I again asked for a manager. None available! I was telling the younger man how upset I was, another man stepped up asking if there was a problem and the younger one replied, "NO problem...." I disagreed! 
I explained and was again told that it is not their fault, there is no way to guarantee a room because they were booked! THAT IS WHY WE BOOKED SEVERAL WEEKS OUT! They said it did not matter, nothing could be done! AGAIN, no manager! 
To make us feel better, they gave us free parking in their facility and a tiny balcony! BIG DEAL! I paid full price for a room without enough beds for 3 HOURS! I then had to wait until almost 5 p.m. the next day for another room! 
Their parking is inadequate...unless you get there at 10 a.m. and never leave your spot...otherwise good luck getting enough room to park! Everyone parks in 2 spaces, leaving no room to get into it! 
We will stay at other Marriott locations! We have told family and friends to go to other hotels! If we are Platinum members, what does everyone else have to deal with???
