Despite booking a Tikal tour through Viator 5 months in advance and selecting from their provided pickup location menu, I was unexpectedly charged a 30% surcharge for pickup on the day of the tour. When I contacted Viator's customer support for a refund, they claimed my pickup location wasn't on their approved list. While this is true now, the location was definitely available in their dropdown menu when I made the booking. Unfortunately, Viator's support team seemed dismissive of my evidence and responded with generic denials rather than investigating the situation. This inconsistency between booking options and actual service, combined with poor customer support, was disappointing.
