Wedding Ceremony Assumptions
. . . the ceremony is just a normal ceremony (not long and drawn out)
. . . there are not a lot of guests (maybe 4-6, besides bride and groom)
. . . you don't mind doing it in a pleasant resort setting
1) A non-Disney-Planner wedding is doable.
2) Not supposed to be, but still quite easy.
3) Process
. . . hire a local officiant (minister or Justice of the Peace)
. . . have your Best Man pick up the officiant, just to make things easier
. . . agree to a scenic wedding location
. . . go through the guard shack and announce the next cars are for the wedding
. . . go to the pre-scouted and pre-arranged location
. . . get married
4) Possible scenic locations
. . . a resort pool area
. . . Fort Wilderness
. . . balcony of a Deluxe resort (eg. Poly, GF, WL) with a great view
. . . somewhere on the grounds of a resort (eg. Deluxe, POFQ, POR)
NOTE: Yes, this isn't supposed to happen, but there are so many weddings in such places, that no CM will ever challenge you. In fact, many will offer congratulations as you pass by. Plus, since it is so frequent, the guards will not challenge you at the resort entrance - as long as they see the wedding dress and you tell them the next 1-2-or-3 cars are with you.
