I am about to ask the same questions- and we will be there the exact same week as you! I think we will be about a day or two behind you on locations though because I am hoping to go straight to VG on the 15th. My son's birthday is the 16th and I think he would love to celebrate there.
I'm a little worried about crowds and having to get to the moorings early since it is a spring break week. I'm trying to make a very loose itinerary and am even trying to leave a day open at the end in case we decide to stay somewhere two nights.
We will be on a Moorings 48ft cat - we have a party of 10 <img src="http://www.traveltalkonline.com/forums/images/graemlins/Yikes.gif" alt="" /> with 6 kids ranging from 9-14.
