Firstly I'd like to warn anyone booking this tour, leave plenty of time to find the place where you board the tram, the address that is given to you is an hotel and is not the exact place to board the tram. It took nearly a hour of searching and asking people around the address that we had been given, we even went into the hotel with the address given to us by Viator as the pick up point, and they did not know were to catch the tram. Eventually after running around for nearly an hour, we found someone who knew the exact pick up point, we nearly missed it, and it was the last tram of the night, we only caught it with a minute to spare. This was our first trip booked through Viator, we would not book another trip with Viator because of all the hassel we had with this one.
The tour was enjoyable and informative. Unfortunately we were unable to locate Causeway Terminus on the date of the tour, so when the bus stop was located the next day, our voucher was not valid and we had to purchase new tickets
