Assuming the initial prices hold until I get the chance to talk to DH (he's working right now, as am I.....so I won't book anything until later today at best), fares aren't as bad as I expected.
We have enough points accumulated to cover one fare, one way, at the tier that includes a checked bag.
The other three fares (one one way, the other round trip) at the middle tier (with the checked bag) the plus the Even More Space upgrade for both of us, both ways would leave us $617.50 out of pocket. Considering that includes upgraded seating, I didn't think that was too shabby at all. It does have us in Orlando for 9 nights instead of 7 (meaning we would need two extra days accomodations outside of our timeshare week) but we could worry about that at a later date. Flight times are such that we could get away without a park and fly hotel, if desired, which would offset that.
Westjet would be almost $1200 CDN with baggage and seat selection factored in, and no upgraded seating. We had thought this might be the year that we reverted back to flying from Toronto, but not at that price difference!
