Still waiting if they recognize and fully refund me, because nowhere in the ticket, description, details, email or such does it say thay we had to show up 30 minutes earlier. I bought our tickets here in TripAdvisor...I even showed the lady in their reception store area, that they may have additional information in their website..but NOWHERE in my confirmation email, tickets or things to do, does it say to show up 30 minutes early. I will change my review if they do refund me in full.
