Perfectly said autjo and Nam, imagine if the wedding was free and everything else was free, people wouldnt just vacation, they would get married or have a huge PRIVATE event everytime they went to an AI. All together you are def getting a great deal! And you have to do basically nothing, they take care of all of it for you. $1200 for a wedding is a steal compared to the states for $20,000 and you have to take care of everything yourself, unless you want a WC (add $5000 here).
So like the autjo said make a budget and compare the costs for your DW to an at home wedding.
