An exercise in extreme frustration
God forbid you use different emails because you will encounter so much difficulty you’ll want to throw your phone against the wall.
Logging in with a Facebook account that uses a different email than you typically book with locks you in to that email. You’ll never be able to change it or see previous reservations.
Attempting to cancel a reservation only results in an error saying “Bad Request: Purchase is owned by a different patron” even if clicking on a link directly from the email reservation. Horrible user experience and a massive waste of time. Figure it out, guys.
