UPDATE: So we secured a group rate with WestJet-pretty reasonable if you ask me. took us so long. Anyways after all that hassle and notifying our guests of this- the majority of them have just decided to wait and book themselves!!! Not through the TA that gave us the quote and is arranging things! So I feel like I stressed over it for nothing! If I would have known they all wanted to book on their own at their own time I wouldn't have bothered wasting months trying to get all these quotes..... oh well. at the same time I feel a bit relieved and like a weight has been lifted off my shoulders. Now everyone can worry about themselves I guess and if they come- great, if not-oh well. I know I am going to have the greatest time ever!
Thanks everyone for all your advice and for listening!!
