If you can't remember how much, it was probably insignificant. I am trying to figure out logistics of getting to Tikal for a couple of nights if I am on the mainland - doesn't have to be by plane, looking for an adventure!
It was insignificant, but then I consider the BZ departure tax as insignificant as well. But much less, seriously.
You know the SA area pretty well, no? Talk to one of the local van operators, sorry no names I recall. Negotiate a driver/vehicle. Of ocurse, there is always the bus...........or hitchhike! (KIDDING!!!!)
