Altitude Rooftop & Pool At Marriott Marquis
There are a number of hotel pools in downtown Houston, but only one of them is paired with a lazy river that’s shaped like the state of Texas. At the Altitude Rooftop & Pool at the Marriott Marquis hotel, you can both splay across an inner tube and lazily mosey around the lazy river until every inch of your body is beet red, hang out in the infinity pool and gaze down Discovery Green below, or get ripped on piña coladas (which you can have poured into a coconut for an extra $20). The Altitude bar does serve food—a selection of light salads and Tex-Mex snacks—but most people here are lounging in a rented cabana or sourcing some necessary vitamin D between conference breakout rooms at the George R. Brown Convention Center. If you aren’t a hotel guest, a pool pass costs $75 plus tax, which gets you an all-day access to a chlorinated paradise.
