"With a stunning rooftop infinity pool and a one-of-a-kind Texas-shaped lazy river, the Altitude Rooftop and Pool located on the sixth floor of the Marriot Marquis Houston is one of the premier hotspots in the city to grab a cocktail and vibe out (yes, even with kids in tow!). Lazying around could translate into springing for a spot at a cabana, pergola, or a day bed with bottle service, or opting for bartender creations. The on-site High Dive restaurant also offers plenty of bites to stay satiated, including coconut shrimp ceviche, burgers, sandwiches, salads, and fruit bowls. Looking to score a spot? Overnight stays come with two to four passes depending on occupancy, and day passes are also available, but plan ahead. Prices vary, and passes sell out fast." - Brittany Britto Garley
