San Francisco, California
tou was good, tour guide- ELi very good. ear piece equipment was awful. It was meant to be a tour and couldn't the guide half of the time as the earphone/ reciever failed to work.
Got an e-mail off Viator to change time of booking. Got to the venue and they didn't have us booked in for the slot, luckily they had two cancellations otherwise we wouldn't have been able to take part. This tour had been booked for months but we were disappointed by the organisation.
