Originally made a reservation for 1 pm, after receiving my confirmation/ticket I got a text telling me 1 pm wasn’t available could I do 3:15. I agreed. Went over to the pick up at 2:45 and texted the driver, he was running behind and said it would be 3:30. There were a number of carriages available so I wasn’t sure why we were waiting when there were plenty of others available. The ride was nice and I would recommend that but I would not recommend prebooking.
