City Information
St Louis



St. Louis is one of several major cities in the state of Missouri and it is uniquely located near the confluence of the Mississippi and Missouri rivers. The city is usually recognized by its most distinctive feature, the Gateway Arch, thanks to which it is the only city in the United States that has a national park in the heart of its downtown district. The Arch is a must-see attraction and you can even take a tram to the top for some incredible views of the St. Louis skyline.
Some of the other truly unique attractions you can visit while you’re in town include the Miniature Museum of Greater St. Louis where you can check out an incredible collection of dolls, dollhouses and vignettes, and the City Museum where you can ride down a 10-story spiral slide (yup, you read that right.) For a great outdoor experience, stop by the gorgeous Missouri Botanical Garden, and then take a stroll through Citygarden where you will find various quirky statues and installations worthy of being featured in your Instagram feed.
Ale enthusiasts would be excited to know that St. Louis is one of the best craft beer cities in the U.S. as well as one of the cheapest drinking cities. That means your party budget could take you a long way. Unsurprisingly, the city is also among the best spring break destinations on a budget.
The main bus and train station in St. Louis, Gateway Station, is located right in the center of downtown, not far from the Gateway Arch, which makes coming in and out of the city a breeze.
San Diego



San Diego is known as “America's Finest City” for its sunny weather, white-sand beaches, and dazzling attractions from Belmont Park to SeaWorld. San Diego's 70 miles of pristine beaches include such gems as Mission Beach, Pacific Beach, La Jolla Cove, and Coronado Beach. The city's strong surfing culture may even inspire you to rent a surfboard and catch the epic waves, bro.
Visitors can spend days getting lost in Balboa Park, a 1,200-acre cultural hub which features 16 museums, immaculate gardens, and the world-famous San Diego Zoo. The historic heart of the city, Old Town, showcases San Diego's heritage and ties to Mexican culture, while other sights like the USS Midway pay tribute to the city's military and maritime history. Leave time for some evening exploring, too! San Diego is rated the #1 best city for craft beer in America, so don't miss out on the bars in the Gaslamp Quarter: 16 walkable blocks packed with nightlife and young crowds.
Two airports, as well as many bus and train options, mean it is easy to get to San Diego from afar or from nearby cities like Tijuana, Los Angeles, Phoenix, and Las Vegas.
