Also,,,agree with above..but do check the tourism
sites for each port by googling it..will give tons of info...then can decide what to see and how to do it that fits your ideas,,not just follow the cruise crowds.Remember,if you go on own,,you MUST be back or ship WILL SAIL with out you.
Also,,do a lot of research on cruise website,,and brochure...for the MANY details about your ship,cabin,cruise,excursions.
I also check the many travel websites,,like Fodors,Travelocity,Frommers,,and get a Rick Steves guidebook(from library)???...perhaps...
After all this,,,have a great honeymoon and just enjoy the cruise...Congrats..
PS,,,remember ,,this is just your FIRST(I hope) of many cruises,,,if you miss something or not fully happy with above,,,can just GO AGAIN...hahaha
