Anyone out there want to share a cabin down the Amazon, across the Atlantic, Casablanca, and on to Rome? The Royal Princess sails from Manaus, Brazil on April 6 for a 21 day cruise. Princess does not offer share prices on balcony cabins, so if I go solo, it gets pretty expensive. Cabin mates does not mean we could not do our own thing. I am a senior straight woman who wants to see the world.
