Summer might be officially over, but you wouldn’t know it here in Houston. Temperatures here rarely reach anything approaching what can be called “cold” or even cool, allowing Houstonians to take full advantage of the plethora of outdoor recreation opportunities and attractions we have at our disposal. This year, Houston’s own Marriott Marquis hotel will celebrate our good weather fortune by throwing three “Second Saturday” pool deck parties. Best of all? The parties are completely free.

Free to the first 200 guests, that is. Better get in line early if you want to catch one of these parties. The Marriott Marquis Houston is known for the massive Texas-shaped lazy river on its Parkview Terrace pool deck which has become one of downtown’s hottest attractions. In addition to the lazy river, the Marriott Marquis also features an infinity pool, hot tub, the High Dive Bar & Grill, and more, making it a true poolside oasis right in the heart of downtown Houston.

Earlier this year, the Marriott Marquis Houston opened up its Parkview Terrace to the public on weekdays from 9:30 a.m. to 10:00 p.m., Monday through Thursday. For $50, anyone can spend the day on the Parkview Terrace enjoying the lazy river, infinity pool, and even the fitness center with towel service. For a more lavish experience, visitors can purchase a $1200 package including a private double gazebo, passes for six adults, chilled towels, and a refreshment package including bottled waters and fresh fruit.

The Marriott Marquis Houston’s free Second Saturday pool parties will be held October 13, November 10, and December 8 from 4:30 to 6:30. The first 200 guests will be allowed in free, so plan on getting there early and waiting in line. Also note that these parties are for guests aged 21 and up, so leave the kids at home.
