There's a TATL crossing Miami to Spain on Princess this May. Rather than return by air, we are making our way up through Spain and France to Southhampton--and taking QM2 back on Cunard. This leg was cheaper than flying back Business class. Of course, it helps to be retired and have the time
But seriously, a TATL crossing is often less expensive than flying Business class. Go figure
So there is always Cunard but I see more lines adding TATL crossings! I see Viking, Costa, MSC, Regent, Holland,Oceana..plenty of choices for a relaxed trip
