c9 | Work & Vacation trying to collide

The Facts:
- I booked off July 23-27 for vacation, and we booked flights with friends to show them the Maritimes (well, Halifax and PEI, to be precise)
- I have been requested* by work to teach July 28-Aug 1 in Edmonton. This requires flying to Edmonton the evening of July 27.
- I currently have a flight from Halifax to Toronto (via Quebec City on Porter Airlines) that afternoon, arriving in TO at 18:55. This flight is cancellable for credit minus a fee.
- It is possible to fly from Halifax to Edmonton that evening and only miss out on the flights with Vinny, Bryce and Daryl, but not miss out on any other vacation time. (option 1)
- It is also possible to return to Toronto with everyone, go home, get another suitcase, and then head for the big airport and fly to Edmonton, arriving about three hours later than the previous option. This only works if there are no delays greater than 30 minutes. (option 2)
- I'm probably going to choose option 1.

* I say "requested" because I could say no, but I sort of already said several weeks ago that that week would be OK, not thinking it was likely. Apparently I've learned nothing about this company in eight years, because of course they would choose that week.
