I read somewhere on here that a lot of places close during October - any ideas as to why? We're schd to stay a week on Ambrigris in Oct & just saw this for the 1st time? Also, we've done the blue hole twice & would like to go out & dive the atolls around that area, but no real desire to do the blue hole again & I know a lot of operations include that on a trip to that area. Any suggestions on shops that will do 3 dives out there & not the blue hole? Thx!
