You are a prisoner here and forced to pay exorbitant prices
It's easy to find a cheap room here through bidding sites, because their occupancy seems to always be low. But once you are there, you are stuck. They gouge you extremely high prices for all extras. Internet available for a fee. 
Are you ready to pay $15 for a mediocre hamburger? Five dollars extra will get you a draft beer. Are you ready to pay $17 for a buffet breakfast? If so, this is the place for you. Food and beverage pricing is exorbitant. 
Might be alright if you are flying out of DFW and arrive at the hotel in the evening, since it is convenient to make an early flight. But definitely don't arrange to stay here if you are flying into Dallas as your final destination unless you have rented a car. Otherwise you will be stranded and completely at their mercy. 
My large room had its only air conditioning ducts located on the wall right beside the head of the bed. Cold air blew right where a person would normally be sleeping. Extremely poor design. I had to shut it off in order to sleep. 
This hotel is far out from the city and a taxi will cost a fortune. No small independent eateries or convenience stores within walking distance. There is a shuttle that runs into Grapevine for $5 during certain fixed hours. 
I've stayed here before, about a year ago, and I should have known better. Prices have gotten even worse. Only suitable for a business traveler on a very generous expense account.
