I tried reading this book years ago but all I associate with it is the Spanish Civil War. I think you're supposed to take an excursion to Granada. BTW, stopped here on a HAL TATL 6 years ago.

RCI has sold TATLs in the past. I remember one for as cheap as ~USD 350 in 2010-11 (from New Orleans). RCI used to periodically move the Oasis class ships to Europe for dry dock, and sold repo cruises for such. They may, in fact, be a way to cross the Atlantic out of season (i.e., other than westbound in the autumn and eastbound in the spring) if one doesn't want to sail on Cunard. The first such cruise was apparently quite a hit as the cruisers could spend time o enjoy the ship rather than visit a port nearly everyday as is the usual 7 day out of Fort Lauderdale(?).

Looks like now that there are at least 3 if not 4 or more Oasis class ships, they rotate them. e.g. stay in Florida until time for drydock where they go to Europe and spend time there until the next ship int he class need to be replaced.
