S.B.
I am a huge advocate of cruising. You depart from the US, unpack once, are totally pampered while on the ship, and you get to stop at various ports. There is a doctor on board the ship if you're worrying about traveling & being pregnant. Spas, entertainment, lots of delicious foods and plenty of activity or none at all...you choose. You will never get more for your vacation dollar than with a cruise! I have been actively traveling all my life (I'm 51) and we take at least one cruise a year. Royal Caribbean, NCL, Princess, Holland America are all preferable lines to Carnival...I would steer clear of Carnival on a US/Carib cruise.
Whatever you decide, happy anniversary! We are also celebrating #10 in Oct (with a cruise, of course) and are taking our 15 month old adopted daughter with us. This will be her second cruise. Adoption, as you know, has been such a wonderful gift in our lives.
