St Johns, US VI

Hi everyone. I almost dont want to ask this but i am giving you all a chance to tell me the TOP TEN things to do on St Johns and also St Thomas. I am most interested in whether any of you have been there and if you have swum open water. Do i need to watch out for weird jelly fish and things like that? I know there is alot of good snorkling so I am sure the water is good for the most part.

So...post away. And you dont have to post 10 things, but one or two if you have thoughts!

Thanks!!

And yea honeymoon...we are going!
