Worth finding your own way from Kissimmee. Bus took 2 hours - over it before we got there. We booked for a Wednesday got no confirmation so tried to change our day also with no reply. This meant we went to the tour at 6.30 that day and waited 2 hours for no bus. Communication from company terrible.
Pick up was not clear since Viator did not gave us the name of the company that would pick us up. It felt a bit uncomfortable when Dolphin Tours came to pick us up from an empty parking lot and the driver could not find us on the list later the guy saw we where on his list and we could join. Rest of the day was more than perfect.
When passengers don't show up at departure time it's their own fault. Don't wait 45 minutes for them only to have them never show up. Wasted a lot of my last evening of vacation.....
