pickup is later tonight and i think both reservations have the same start time.

is it considered ok to not use a reservation and not notify the rental company / location at all, or not until after the start time? that doesn't seem real polite. but if you cancel #2 before picking up car #1, then i don't see the benefit of having the backup reservation.
