The Port Marina is just a stone's throw from Kings Bay, and the manatees. A pontoon boat rental is $95 for 1/2 day in the am, $125 for 1/2 day in the pm, or $150 for all day. It's about a 15 minute ride from the marina to 3 Sisters Spring, so you can see 2 locations and look for manatees. If you start at 8:00am, you can hit both locations with plenty of time at each spot. I'd be in for this if you'all wanna meet there for a trip. The boats are 24' and will hold 12 snorkelers, and 8 divers wth equpment. I'm in Lecanto, just east of Crystal River. I'd be happy to make the reservations. I'll be out of town 11/12-11/16, but am open any other dates.
