We rented a bus to give our wedding guests a tour of the strip after our ceremony. It was SO cool, the staff were really awesome, and the guests loved it. The bus ride was smooth, the process of renting the bus/dropping off drinks was easy peezy, it was super affordable, and the bus looked really cool.
Side note: make sure you check the weather ahead of time and communicate with your guests-- we were freezing because we're all from the Midwest and assumed Vegas would be warm, haha!
