Nice hotel on west side of Houston
I stayed at the Marriott Westchase for a conference/camp during June of 2012. Overall, I had a very nice experience at the hotel. First, the rooms were in great shape. It is what you would expect from a Marriott - comfortable beds and nice toiletries. The housekeeping staff was also quite friendly and cleaned the rooms promptly. Regarding the amenities, the hotel has a nice indoor/outdoor pool and a fairly extensive fitness center. 
My only complaints would be the food. I will not we used catering, but the food was rather simple and bland and often ran out. The staff were friendly about it, but the problem did not improve over the week. 
If I was back in the area, I would stay here again
