i have heard barb from barbsbelize.com is terrific.
in 1993, i think it took about 2+ hours drive to get to san ignacio (cayo) from the airport. does that sound right everyone? there is just one road that runs east to west, cant miss it. we also rented a 4x4. it was a lot of fun. the adventure of a lifetime.
the jungle and ruins are there too. you can see photos at http://ambergriscaye.com/jane
