Tchan03,
The coach that you saw in
Disneyland, is probably not the same coach they use for WDW weddings. I know that they use a different one for California weddings then they do for Florida weddings.
Was the one you saw in DL decorated in vines and flowers and look more "fairy princess-ish" ? If so, then it is different. But both are very beautiful and you would be very lucky to have either one.
Then again, maybe it was the same one. I justwanted to let you know that there are two different styles of coaches out there.
Also, if this helps anyone, Cinderella's coach is only permitted at certain wedding locations and the Contemporary is not one of them, for obvious reasons (there is no wedding location there). Unless you were getting married in the MK, I do not believe they would even allow you to take a carriage ride there.
Besides Cinderella's coach, you can rent a Landua coach which someone has already mentioned. This is a standard open aired horse and carriage, pulled by one horse I beleive. Still very beautiful! I belive these are only available at wedding locations as well. If you want to take a ride in one and not use it for the wedding, they are available for evening carriage rides at POR and Fort Wilderness. Hope that helps!
