I booked a 'skip the line' ticket for the Paris Catacombs, advertised on TripAdvisor's "Viator"…read morecompany and apparently offered by My Genie in Paris (Voyages LLC) according to my receipt. This type of ticket is 3 times the face value of getting in a venue. It is supposed to allow you to, well, skip the line, as the name implies, to enter the venue on a preferred basis. That was not the case for me. I paid premium dollars, had my ticket, was standing in the correct line and the 'Soup Nazi' making the entry decisions went to the general entry line and let in hoards of people waiting who were only paying the face value of the ticket. Hey, that is great for them but leaves the rest of us feeling like complete chumps. Soup Nazi finally graced us with his attention, only to then again cut in front of our group with some other people who apparently had booked Super Deluxe Ultra Swanky Your Mother Wears Army Boots tickets. This was a complete waste of money and I would have gotten in the venue faster waiting in the regular line. Now I will have to dispute this with my credit card company because Trip Advisor has no email contact and I see from these other reviews that trying to get anywhere with this tour operator is going to be a worthless waste of time. DON'T BOTHER BOOKING SKIP THE LINE TICKETS THROUGH TRIP ADVISOR/VIATOR/MY GENIE IN PARIS. They will process your credit card but you won't get the service you are paying for. Just go to the catacomb early in the day (before they open) and I'm sure Soup Nazi will wave you right in.

I wish I had done some more research before booking this. Unfortunately I also booked through…read moreViator and my money was gone before I found out who the tour operator was. Same experience as everyone else - the guide was a no-show and all the calls on our Viator confirmation went straight to voicemail - still haven't received a return call. I can't believe that Viator would continue to act as accomplices for these scam merchants.
