The 1,000-room Marriott Marquis Houston is an upscale hotel located in downtown Houston, adjacent to the George R. Brown Convention Center and the Convention District MatroRail station. Popular with business travelers, this hotel has large, comfortable rooms with great amenities and big windows, most of which offer great city or Minute Maid Park views. Dining options get consistently great reviews, especially its Mexican restaurant -- helmed by an award-winning chef -- and the sports bar. However, the highlights here are the wellness and fitness facilities, which include a top-notch gym with personal trainers and free group classes, a spa with tons of treatments and salon services, and two wonderful pools with a striking Texas-shaped lazy river. Travelers seeking residential-style accommodations in this area may want to compare rates at the Embassy Suites Houston – Downtown.
