She is going on like her 8th trip of the year for a whole month...too bad. She is always on holiday vacations so timing my montreal visit with her would be impossible and I dont want to go in december. It is okay.  

UPDATE

I found  a ticket for 5 days at less than 500$ in the first week of october. I may pay for  a cancellation policy of 75$ at that price. We'll see.
