the carriage rides at port orleans riverside is a relaxing/romantic 30 minute ride around the resort & river. and the other is at fort wilderness which is a 30 minute relaxing/romantic carriage ride around the fort wilderness grounds & bay lake. call 407-wdw-play (939-7529) to book either.
i also remember a hayride excursion from the fort wilderness which gave a glimpse of the fireworks but not sure if this is still offered.
any other questions just ask, hope you have a great wdw honeymoon!
i myself am getting married at wdw next year.
