“So I booked a "Cardiff Bay Boat Tour" for my father and I on September 30 for an October 29th boat tour (almost a full month in advance). The day before the tour was meant to take place, I received a message on Viator indicating that there was a scheduling conflict and the boat tour we were meant to have around the bay wouldn't be taking place and we were going to be "upgraded" to the Aquabus tour and they asked for a preference of time.
