Terrible Service- Stay at the Marriott across the road
We stayed here because we got a discount for being a transplant patient at the Methodist Hospital. When we arrived there, we waited in outrageously long lines to check into the hotel. Then when we get to the hotel they took forever to check us in and were very rude. One of our rooms, they would not honor the medical discount for the caregiver and charged the full rate. We were told all rooms associated with the patient would be given the care giver rate. 
The staff were incompetent. We ordered breakfast downstairs in the lobby and we got oatmeal, a parfait and frenchtoast. It took 30 minutes for someone to help us. The waitress took another 30 minutes to get the check together and messed it up twice at the end of our meal. It was also outrageously priced at $32.00 for those three items. We did not end up eating there again the rest of the trip because the services were bad and the food was way over priced for what you actually receive. 
Parking is $15.00 a day. It is outrageous. Plus, they are not helpful at all in setting that up and the room keys never work like they are supposed to when you try to leave the parking garage. Nevermind, how rude they were when I was trying to set everything up for the parking. The women there had so much attitude and honestly acted like it was thier first day on the job.
When we would try to get any service, the workers would all chat at the front desk and interupt my conversation to talk about gossip. They seemed very disconnected from thier jobs and very resistant to wanting to help. We all felt that we were imposing on them by staying there, which I have never felt at a hotel before and I have been traveling all of my life. 
Only PROs were the gym was ok and the rooms had comfortable beds. Usually hotel beds are not the best and these were very comfortable. 
Good luck to you if you decide to stay here!
