As a single, I read your article with great interest. FYI America West/Alaska sightseeing offers a great deal - that is if you can tear yourself away from no casinos, no shows and formal nights - very easy for me. On two of their ships they offer NO singles supplements whatsoever. There is an itinerary on the Spirit of Alaska, one of the ships they talk about that will be perfect for me. But next year is the Cruisemates Baltic cruise, the year following is Brazil for plastic surgery, so who knows what it will be like in 3 years. Maybe someone else can take advantage of it. Adventure cruising is the BEST.
You said in your posting that you are going to Brazil for plastic surgery. If I were you I would be very careful abou the surgeon you go to. You must remember that the medical standards in other countries are not the same as they are in the United States. You get what you pay for. I am not trying to be nosey but I don't want you to go through any bad experiences.
