US2U uses a bus company called XcursionsUSA. When I booked I thought the prices were reasonable, and I was excited and ready for my trip. I was told that my meeting point was a hotel 1.5 miles from the one I was staying at. So, I got up early and walked the 1.5 miles to only get on the bus and go pick up more people directly across the street from my hotel! They never asked where I was staying and I ended up waking up earlier than I needed to and walking in the humidity. As if that wasn't ridiculous enough, on our way back to Miami from Key West, 4 lug nuts came loose on one of the wheels on the bus! This left us stranded for FOUR HOURS and we didn't get back to our hotel until 1:30 in the morning. Loose lug nuts should never be an issue, this company clearly does not use reliable mechanics and our lives were endangered. If something as simple as lug nuts was messed up, what else could be messed up? Book with someone else and make sure your bus is not a XcursionsUSA bus.
