I stayed at the Marriott Hotel at the George Bush Airport in Houston, TX after traveling from the Middle East and flying over 24 hrs. I was tired and exhausted and was willing to pay the $300 a night for the convenience and (assumed) luxury that I thought this hotel would provide. When I called the hotel for the shuttle bus to pick me up, I was told that I had to take the underground subway system. I had a ton of luggage and luggage carts are not allowed on the subway. I was not happy about this but dragged my luggage down the elevator and on to the subway. Once at the hotel, I saw a sign that said the subway system would not be working again until 7am the next morning. This created a huge problem because my flight was at 6am and the hotel said they did not have a shuttle service. When I got off the shuttle, I called the phone by the elevator to ask for assistance with my luggage. I waited 20+minutes and no one showed up. I dragged my luggage upstairs to the check-in counter where the customer service was luke warm. I explained my need for shuttle service to the airport the next morning--I was then told that they did have a van to provide transportation to the airport but they do not like people to know about it and prefer people to take the underground subway system. I thought that really stunk that they lied about not having a shuttle service even after I explained that I had just traveled from the Middle East and needed assistance with my luggage. I was then told to make a shuttle reservation with the concierge. I then went up to my room and was surprised at how old, dated and used all the furniture looked. I have stayed at other Marriotts for $100 a night and saw brand new furnishings. This room looked used and abused and was not very clean. I had been in my room 10 minutes when the door swung open--it was the maid service. They did not knock before entering and simply unlocked the door. When I looked startled, the maid told me..."Well, you should put the bar across the door". Wow, talk about rude. Before going to bed, I called the concierge to confirm my reservations--of course they didn't have it. I had to make another reservation. I called the front desk to request a bell hop come to my room to assist me with my luggage for the following morning. I called back 30 minutes later to confirm that service--again, no record of my request. I woke up an hour early to prepare myself for no shuttle or bell hop service and I'm glad I did. The bell hop never showed up and the shuttle service was delayed due to all the people that needed service to the airport. I waited for 3 rounds of people to be taken to the airport before it was finally my turn. I was so disappointed in my stay and the waste of money that I called the Marriott to complain--the customer service rep did not apologize or do anything to rectify the situation. In conversing with other travelers on the shuttle, I found out that their experience was similiar to mine and they were disgusted with the lack of quality service and cleanliness. Marriott Corp. should be ashamed of the service at this hotel and look into making some serious changes.
