If you are flexible about when you go, I'd suggest looking at Moorings/Sunsail. The options for taking out other boats is very good. We own a Moorings 43.3 monohull, but have only used our own boat once, another 43.3 twice and Cats all the other times with over a dozen charters completed now.
We are keeping the 43.3 after its contract is up so that helps, but we are also getting tremendous value by upgrading to cats while we can.
