I'm leaving to Belize this wkend. I'll be in San Ignacio first, then fly to San Pedro from Municipal airport. Since my itinerary is still up in the air on my last day in San Ignacio (not sure whether to stop by the Zoo), I haven't yet booked my flight (Tropic Air) to/from San Pedro. Will it be any trouble if I just show up w/o reservation?

Another question - My flight back to the US leaves Belize Int' Airport at 12 noon. How much time do I need? Do I have to get to the airport at least 1.5 - 2 hrs before departure? What time should I leave San Pedro?
