I feel your pain Betty! We finally booked our ten rooms but it was soooooooo ridiculously painful and took a friggin month of emailing back and forth with guests, my TA, Westjet and Dreams.
The whole thing was so frustrating and stressful that if I could do it again, I would have let everyone do it on their own. Aaand, neither of FI's sisters have booked and now prices have gone way up! Poor FI
