Fly straight to Peoria and rent a car from the airport. If you are coming from Miami, explore flights from Fort Lauderdale, as often times, they are significantly cheaper for direct flights to Peoria. You can also look for options through Allegiant, although the days of travel may be restrictive.

Bloomington is 45 minutes from Peoria, and may have better dates/ prices for flights through Allegiant. You should be able to rent a car from here as well

This is the biggest airport near Peoria. It is 3 hours away from Peoria, but may be a great opportunity to take advantage and see the city! You can rent a car from here and drive down before the wedding!
