Hopper's confusing system and unauthorized charges scammed us out of hundreds of dollars. Hopper couldn't understand that the app put a wrong booking because another hotel through them wrongly charged us. They refunded some of the money but it vanished by morning. We'll contacting our lawyers and credit card company to fix this. We paid booking insurance, VIP service and all other protections and it still happened. So far we've spent over $900 all we have booked is 4 nights in a cheap La Quinta.
