Drive a rental car from the airport to the Red Rock Casino Resort and Spa, a sprawling golden-age Vegas property overlooking the Spring Mountains and the Red Rock National Conservation Area. You'll be close to the best hiking and rock-climbing in the area, but still able to gamble the night away.
Drop your bags and go for brunch at Public School 702, a modern gastro-pub with craft beers, patio games, and communal seating. The schoolhouse theme may sound trite, but it works, and it doesn't hurt that their servers are easy on the eyes.
In the afternoon grab the free hotel shuttle to the Strip, and visit one of the city's many luxurious pool complexes. Try the Golden Nugget, one of the best in the area, with a three-story water slide and famous Shark Tank. If it's Sunday, the Luxor hosts a gay pool party complete with barbecue and DJ beats. The pools at Caesars Palace are also a good bet.
When it heats up later in the day head indoors at the Red Rock Climbing Center, where instructors lead a daily series of challenging bouldering and climbing exercises. There are three floors of climbing walls at a variety of skill levels, and both top-rope and lead climbing is available.
Dinner is at Veggie House in Chinatown, serving an all-vegetarian menu of Chinese noodles and stir fry made with fresh, wholesome ingredients. Order their small plates for the whole table so you can try one of each dish on the menu.
After dinner relax with a few drinks at The Phoenix Bar and Lounge, a low-key bar with karaoke, drag shows, and video games. The vibe is super-relaxed and inclusive, and the crowd is usually mixed gay/straight. After a few rounds of karaoke head back to the hotel to rest up for the next day's adventures.
