Left amusement park ticket info on work computer (through work email) and am a state away... Anything I can do to not have to buy a new one?

Just looking for ideas if anyone has any, don't know of any way to access my email on a personal computer (was through some office outlook client) but wasn't sure if cancelling the transaction would be an option.

EDIT: got it figured out, forgot about a coworker who lives near me that could get into my stuff, thanks anyway all
