Hi,
I did this year before last and it was so much better than Discover Cove, (which I loved every minute of as well!) I think becuase the manatees have a choice in it.
Here's what I wrote about it then, sorry it's so long!
I went with
http://www.fun2dive.com . The bloke who runs it is Capt Joe Detrick. You couldn't ask for a nicer bloke to go with, definitely knows his stuff, his lists of qualifications and previous jobs (wildlife photography, working for Disney, Sea World etc) was very extensive. The manatees swims are run Oct-Feb. Only six people as taken a day and all wetsuit. snorkel and flippers are included in the price ($85).
You have to be at his shop in Sanford ay 6am (very easy to find with his directiosn) and it takes 45 mins for I Drive. There's coffee waiting for you and when everyone arrives he gives out the equipment, gives a talk on what's allowed and what isn't (no going into the sancturies, no chasing, no swimming underneath, no holding etc). You watch a video and then sign a disclaimer to say if you do any of the ablove and you get caught he isn't responsible and you have been told. The fines are $100,000 plus.
You then get in your car and follow him to Crystal River for about 9-9.30am, stopping for breakfast along the way. Then it's off to his little boat and to wherever he thinks the manatees are going to be. Once there everyone gets in (including Joe so make sure everyone's okay).
Admittedly I found it a bit scarey the first time one swam underneath me as where we were the visability was about 10 feet, water was about 16-20ft deep. There no real current so it''s not much different form swimming in a pool.
I had some problems anyway as I suffer from claustrophobia and I couldn't cope with the snorkel because of it (made me panic) I was going to give up and get back in the boat and just watxch,even at this pooint though just being on the boat and seeing them in the water would have been worth every single penny!.As I was holding on to the ladder on the boat in the water trying to calm down a manatee suddenly appeared next to me. It was beautiful! It stayed with me for about 20 minutes rolled on to it's belly so I could scratch his tummy for him. I decided to give it another go after that and must have seen another 6-8. THe rest of the group went off to look into the spring we were next to were there was some big fish.
At about 12ish Joe told us all to get back in the boat to have a rest and omething to drink (Drinks ,fizzies and waterand trailmix was provided free).
There was a piece of rope hanging off the boat as Joe says the manatees like to use it as a chewing toy. While we were having a break 2 manatees came over to play with it. Some us got back in the water with them and they stayed with us for the next four hours. In that time others did come over and at one point we were surrounded by about 8. They are so gentle at no point do you feel threatened, even if they hit you by accident with their tails it's just like being very gently pushed. A mother and baby of about 3 months came over at one point as well.
I really can't recommend this to you enough, it was the most beautiful and moving day I've ever had. I really can't describe how special it was! I think it was also partly because they are wild, if they come see you it's completely their choice to stay or go.
You can also buy a video ($40), but you have to let Joe know before you leave that you want one so he takes the video camera with him and you can also rent underwater cameras for $25 with a roll of film. Both were really worthwhile.
We did see some other tours out and a was so glad I hadn't gone for a cheaper shorter one. They had more like 12-25 people with them and there was no way they could all be watched by the people there plus they didn't seem to have been told what they were meant to do (like keep quiet otherwise you scare them away) plus thry left before they'd seen more than two. Joe really did know what he as talking about. Also if you've got kids it'd probably feel a lot safer in a smaller group.
If I have missed out anything you wanted to know please feel free to ask, I've bored everyone I know with it!
Cheers,
Zoe
