the "office" is Mrs. Nunez.

i have never used excaliber, and do not know anyone who has, so cannot comment on that. i do know these two things - daniel's expertise is in nature & history, (i suspected he may subcontract something like a zipline tour), and while at lamanai, another popular tour group arrived after us, and left long before us. our tour was maybe an hour longer. the home-cooked lunch rocked too (my 12 yr old who eats nothing went back for seconds!).

otherwise, one can either assume one 'gets what they pay for', or go with the best price. strictly your call.
