If you are staying at FA then just use the inhouse on site dive operator..It really is a no brainer. This way you have them right on the property if you need anything,no running around/phone calls to find them if elsewhere. Dive house has lockers on the dock at FA and you have access to tanks to shore dive as much as you wish to. I took a group to Casa Del Mar last May and DH was one of the operators there.No problem with the diving on their boat,as it had protection from the sun.Only issue I had was that they had to transport their tanks to Casa from FA for shore dives as they had no property at Casa and only were there on request.Life would have been easier if they had a bit of property there that is their own. I escourted the trip but had nothing to do with choosing the property or dive operator as the LDS owner did all that leg work and assigned me to work it.
