My husband and I are going to Florida to dive BHB on Aug 31-Sept 2. It will be our first time there. It has been suggested to me that we should hire a guide for the first time we're on either side. However, I'm trying to make this trip as economical as possible and don't want to hire a guide if we could meet up with someone who is familiar with the sites and who is going to be diving at those times anyway. Does anyone here fit that description?
