Any recommendations as to how to go about doing the manatees. As in with who and time of year. I have heard winter are the better months?
With in-laws there I am assuming during the week may reduce the silt-up problems more.
Yes - avoid weekends. Winter months are best as there are Manatee in lots of areas.
Unlike ocean ops, because all the operators use these small little pontoon boats (max 8 divers or 1,000 snorkellers) it is best to go with the biggest op in the area - American Pro Diving - extremely professional, and have boats docked all over the place or trailered so they can get where they need to go.
Also the Homosassa River site is much less visited (APD has boats docked to reach here, no one else really does)and has a larger viewing area, However the visibility is slightly less and the muck gets stirred up quickly - often by the Manatees. If you go to the left bank you have a good area if you can get a couple of them over there.
If you do any of the Crystal River sites - keep away from the buoyed off areas and go from boat to boat. There is normally a couple of manatees playing with the boats and you interact in a little quieter environment.
Don't dive Kings Cavern unless you are the only dive group there. Rainbow River drift was OK (no Manatees) and worth doing once.
Wish I had done Blue's Grotto or Devils Den while I was there, but I didn't have time.
