Of all the hotels opening in Houston ahead of Super Bowl LI, the Marriott Marquis in downtown is by far the largest.

At roughly 1,000 rooms, the 29-story building at 1777 Walker — near Discovery Green — is truly Texas-sized. So it's fitting that one of its rooftop water features is a 530-foot-long lazy river in the shape of the Lone Star State.

Recently, a photo of the river lit up for the first time was shared by the Greater Houston Convention and Visitors Bureau's Facebook page, and it elicits serious Texas pride. For scale, the lazy river dwarfs the hotel amenity deck's infinity swimming pool. (Story continues below.)

It's only a matter of weeks before you'll be swimming in one of these pools — let's hope they're heated. The projected opening date for this towering has yet to be determined, but a spokesperson tells us it should definitely debut sometime this winter.

Developed by Houston-based RIDA Development Corp., the downtown hotel will have a skybridge connecting it to the George R. Brown Convention Center. Inside the hotel is an upscale sports bar, which is being launched by Astros Hall-of-Famer Craig Biggio. Dubbed Biggio's, the sports bar will offer steaks, burgers, craft beer and cocktails.

The hotel's dining establishment will anchor upcoming restaurant row Avenida, along with three-time James Beard Awards finalist chef Hugo Ortega's upcoming Xochi.
