Viator double booked our trip with 90 extra people for the everglades tour. When we arrived 45 mins early to check in we was told that there was no room for us that they have been arguing with viator for the last 6 days cause they won't stop selling ticket to sold out events. Once I got customer service on the phone they wanted to send me off on a night party boat 3 hrs later instead of giving me a refund well I had prior plans and couldn't do the party boat tour so I was told they'll try to get me a refund. Very rude and argumentative.... I do not recommend using viator ...
