We choose a resort (Azul Sensatori, Mayan Riviera) and keep getting our TA to get updated prices until we were happy. The TA we choose deals only with destination weddings (Weddings By Oceans) and has also managed to get us a number of 'upgrades', 20% off our reception costs, free cocktail party. We have done some group rates for Toronto and Ottawa guests (and had to pay a deposit for these). And our TA managed to arrange a great land only rate (ie all inclusive Hotel) for those guests that are flying in from other locations. So most of our guests will be between $1500-$1800. And we have guests coming from Edmonton, Saskatoon, Yellowknife, Toronto, Ottawa, Halifax, Moncton and a couple from the US.
Good luck everyone! I know this was the most difficult part for us...and now the waiting for people to book is killing me
