I wish these guys would follow AirBnb in at least pretending to care about design. I know Booking.com is trying, and for that I can retain the knowledge of going directly to Booking.com/AirBnb.

TripAdvisor's site is a nightmare to navigate. It's easier to find things by searching them on Google than trying to navigate TripAdvisor. I won't lose sleep once someone finds out how to arrange their information in a cleaner format.

I once booked trough booking.com

When I arrived the hotel had all my credit card detalis printed on a paper that was just sitting there.

Never booked again trough that site.
