It's true, but I wouldn't cancel if I were you. This might be a stupid question so I apologize in advance but can you only get the refund if you don't go on the tour, or can you take it and still get one for false advertisement. If you can't take it and get a refund, I would still go, the experience just won't be completely worth it. Basically I'd say go either way but they should let you get a refund and go. I think if you haven't booked yet(I know you have Arsik, but I'm just saying in general), don't, unless they change the policy, or lower the price
