Flight
Orlando International Airport is a better choice to fly through due to its proximity to hotels, rentals, dining, Disney, and Downtown Orlando. It is also closer to the wedding venue and generally has more flights available.
Flight
Orlando Sanford International is the less convenient of the two airports, as it is approximately 30-45 minutes from all the 'action.' You may find cheaper flights to this airport, but will end up spending more on an uber if you do not intend to rent a car.
House Or Rental
The hotels in the area are in the $200-300 a night range. Renting a home from a private owner may be more cost effective, especially for larger groups.
