We're flying into BZE on the 6th and renting a car, we want to return the car & fly to San Pedro on the 10th but haven't booked a flight yet as we don't really know how long the drive from Lamanai to BZE (international airport) will take us.

I have read that just showing up at the airline before the 2nd to last flight of the day and buying a ticket directly should work, but I don't want to allow anything to go wrong.

If anyone can estimate the amount of time that drive from Lamanai to BZE would take I could just book a ticket now & prevent anxiety!

thanks!
