It's Miami, so partying is going to be a serious business. On those nights when you're looking to take the party out of the club—but not back to the crib—the Hotel Tonight app comes in. You can get fast, same-day bookings all the way until 2 a.m. If you're stuck in a snag, the app also has 24/7 real-person customer support. Feeling a little tipsy, or not in the mood to bring the phone to your ear and talk? You can connect with customer support through the app without even calling.
