Just ran into an "interesting" bug. I had pulled up availability/rate checks for the Park Hyatt Beijing and Park Hyatt Seoul (in that order) for different dates in two separate tabs in Chrome. When I clicked through to actually reserve the room at the PH Beijing, the dates and rates that appeared were for BJ but the hotel name, photos, and everything else was for the PH Seoul. I'd hate to have seen the reservation I ended up with if I had not been paying attention and just clicked through on autopilot.
