Well... at the departure site the operator stated that he never received the reservation from TripAdvisor, that it was the 2nd time in 2 weeks that this happened. So, I did not get to go!! VERY Disappointed!!
This was right after another tour operator, that I booked via TripAdvisor, for the same type of trip, cancelled my reservation at 5pm the might before, for 'reasons beyond his control'!!!!
My advice.... in Porto, don't t use TripAdvisor to book your trips!!!
