Did further research and found that there's only TWO flights of that day and if I book, it will be the first one and the next flight is about 2 hours later on still tiny plane if denied boarding on first one.

I am concerned because the cruise leaves next day from Quebec and i know there's many people needing to go the day before from various places & various airlines but this one only have two departures the day before on a tiny planes...not enough seats.

Still thinking...ugh!
