I always ask 'Where are you staying?' to avoid spending a lot of time and email exchange with some on who might be on a cruse ship or staying in Placencia.
Yesterday I exchange emails with a lady that wanted to do the Blue Hole,Turneffe, Hol Chan Shark Ray, Lamani and visit Bacalar Chico reserve and what ever other trips I could suggest. She wanted to purchase a package, we exchanged 4 emails and then i discovered shes arriving on the 11th departing on the 13th.
