I've been on several boat trips - a barge cruise in France, a Danube River cruise, a sail along the Nile - and always the accommodations have been lovely. Sometimes very lovely. But it took a Mississippi River Cruise from Memphis to New Orleans with American Cruise Lines to reach luxurious.

Foreign countries may close their borders and airlines cut their flight schedules, waiting for Covid-19 to disappear, but that doesn’t mean you can’t treat yourself to a vacation this year in a Colorado hideaway as safe and solitary as it is remarkable.
