Depending on the size of your wedding party weddings range in the $3,000 for up to 13 guests but if you want more guests you have to have a Custom wedding which is a minimum cost of $7500 in the week (excluding taxes and gratuities) or $10,000 for a Friday - Sunday.
If you had intimate the coach would be $2,500 but if you went for the Custom then this $2,500 would count towards your minimum costs as would the $2000 + venue fee for the Wedding Pavillion, which is a very popular venue for brides. If you were having the intimate I think you have to upgrade to the Deluxe package to get the Wedding Pavillion.
We have a guest list of 40 and no coach and we're already way over budget so it's easy to start racking up the costs.
If you want to have the whole event in the Magic Kingdom - this ofcourse has to start after hours so it's best to get marrried in the off-season when the park hours are shorter but if you want the event to happen in front of the castle that starts at a minimum of around $50,000 give or take a few $1,000.
Private fireworks are very very expensive IMHO but I can't remember how much. But you can always arrange to have a private Illuminations Dessert Party in a special roped off viewing area for you and your guests at Epcot - I think for 40 guests it's working out at around $1500 but again it depends on what menu you have served
