We went through the same thing!! i went right to the source. Ok here is from our experience, We wanted family suites in our hotel. But before they were to get pricing we need to have deposits down to promise we would take them. NO WAY! I'm not promising something i don't know the cost upgrade. So we went with regular suites. And what you can do like us is talk to the hotel when you get there or close to the date for upgrades. Second. I like to get the info from the horses mouth so i phoned West Jet Vacations and (if that's who you are through) they told me for every 16th person is free. Adults only not including kids. Also they will take the lowest fare. So if you have guest flying in from somewhere else and there amount is cheaper they will take that fare. Also its a max. of 2 free. With the wedding stuff ask the hotel what they can do for you close to the date as well. That's what I have planned as Westjet has been nothing but no answers. I hope this helps
