Marriot.
Ritz Carlton
Each team gets to choose where they stay, so there is not any specific hotel.
Im not sure anyone would know that info, but Im guessing any fancy hotel nearest to the Houston stadium
opposing teams usually stay in a hotel a very expensive hotel
I'm assuming that all the Dallas Cowboy players live in the metroplex, so I'm sure they all stay home when playing at home. Actually the cowboys all stay at the Gaylord Texan before a game
They are staying at the Grand Hyatt but unless you are a guest its kind of hard to access to the hotel inside. You can probably watch the team exit the busses but getting inside to hang out may be tough....thats why I booked a room there 3 months ago...:)
I heard either the omni or westin but i know other sports teams have stayed at the hilton. let me know if you find out please 2604795548
Gaylord
You are SOL! there are some hotels that offer shuttle service for an additional cost to your hotel stay. Looks like all is well in greedy a&% America.
Hotel Crescent Court is a hotel in Dallas you should stay away from. According to many reviews, people experience bad customer service and the rate is much higher compared to others.
Either the Ritz Carlton or the Arizona Biltmore
