This has been a source of stress for me also. Often times people can find things cheaper online because might only be 4 or 5 seats at that rate, but the group rate (average price over 10+ seats) might be higher. I didn't believe my TA when she explained this to me, so I called around for different group rates and this was often the case (i.e. the group rate for WestJet was more expensive than the seat sale online). I was lucky that Sunquest was offering a deal where you can reserve 30 seats for 90 days and you only have to pay two deposits. After the 90 days, they just release the seats that were not sold. We also got price drop protection so that if the group rate went down, we'd get a partial refund. The deadline for my group to book was October 15th -- and let me tell you, I had plenty of people tell me that it was way too early to book and that the price was too high. Our group rate was $1610 (taxes included) for the Majestic Colonial, departing Toronto on January 29th. We checked the prices again last week and also got everyone a $110 refund, making our rate $1500 per person! Not bad for January/February, I think. Anyways, a couple of people were still dragging their heels and said they will wait until 2 months before the wedding to book. No one believed that the hotel might sell out. I decided to check the rates yesterday and found that there are no packages left online! So here we are, still 11 weeks until departure and our hotel has sold out. I feel bad that at least 2 good friends will now have to miss our wedding or stay at another hotel, but I'm happy I did go with a TA in the end. I'm just barely containing my "I told you so" comments to my groomsmen, who complained until the very last minute before our deadline.... Good luck ladies! And don't let your guests wait too long to book....
