Not familiar with that ship
but being that Island Cruises is a joint venture between Royal Caribbean Cruises Ltd and First Choice Holidays you can hardly go wrong.
You, your husband AND (especially) your daughter will love it. I also agree with Sonny in that the "week at the beach" after the cruise could be anti-climatic. You might consider doing the beach first and end with the cruise. Sort of ending with a "BANG"! Either way, have a great time - the Med is fantastic - I love it!
