This looks to be a good opportunity for a trans-Atlantic fanatic since this ship is heading west just as several other ships are coming in to home ports in Europe, from their Caribbean winter homes. Check it out by doing a custom search on VTG, region "transatlantic", departing April 1-18. A perfect fit is the Crown Princess. Arriving from Galveston, through Ft. Lauderdale, exactly on the 30th.
I am not a sea day dog so it won't be me trying this. Good luck irishthor
