We're having a bus and a limo. The limo will be to take the bridal party from the GF pictures to the WP for the ceremony, and then it will take DF and me to the reception.
The bus will pick guests up from disney hotels, bring them to the WP, and then bring everyone to EPCOT for our reception. It will then bring everyone, including us, back to our hotels at the end of the night. Anyone that drove to the WP (staying offsite) will take the bus to the GF and walk to their cars.
Hope that helps.
