Cindy, Regent did this to themselves. While all (almost all) of the cruise lines except Regent and Oceania set up new round trip itineraries, Regent and Oceania wanted to retain as many original itineraries as possible. London to Barcelona was always going to be problematic. London round trip is not problematic if Regent would realize that it only works for UK residents as long as USA is Amber and requires a 14 day quarantine. Not going to change anytime soon since USA recommends against travel to UK (and now Portugal and Spain).

With the new itineraries UK residents can't go (due to stops in France) without having to quarantine on their return. I think these first two itineraries may sail with only 20-30% passenger load. Shouldn't be a problem once they get to the Med.

Just my two confederate sense,
