I have a hellish day of travel coming up, going:
YYZ-YVR-YUL-YYZ-LIM within 26 hours.

(I got a great fare a while ago, before I needed to be YYZ. Heading back to YVR to start my original itinerary was cheaper than the change fees, it will also put my within spitting distance of SE)

My question is, what would you experts recommend for my checked baggage?

I see three options:
1. See if they will check it at 6AM for my midnight flight YYZ-LIM
2. Check it through with me on the whole itinerary (first segment is different PNR)
3. Store it in YYZ, necessitating an exit of the secure area, retrieve the bag, check it in and chance missing my pasta dinner in the lounge.

Any tips/tricks/advice are greatly appreciated.

If anyone wants to give me eups, it would be even more appreciated!
