Thank you all for the tips and comments. I contacted our TA again today and asked the same question can we change things if disney comes out with a promo, and again she said unfortunately no, it's a waiting game. She is pushing for me to book a package with west jet or aircanada , maybe that's the reason we can't change or maybe it's a commission thing, however thanks to all you helpful folks, I will do as much of the legwork as possible and find a new TA when our feb prices are released, hopefully soon!
** also the TA is telling me that a package with flight will less expensive by far but flights will land late...from what I've seen, flights separately so far are cheaper and earlier , mind you our vacation is beginning February so I can't be sure about that statement yet**
Thank you all!
