Before our trip, I watched dozens of videos on door and cabin decorating. Most blogs and bloggers talked about buying or making customized magnets to hang on the door or hanging magnetic hooks on walls for extra storage. Well, we quickly learned that some of the walls were not magnetized at all in our cabin. Talk about disappointing! Luckily I had brought command hook strips and painter's tape. Try to google your specific ship to find out what is/isn't magnetized in your specific cabin type. For the Vista, the wooden wall panels and the cabin room door are not magnetic. The panel next to the door is magnetic.
Here are some doors we passed by that were decorated:
Another things many blogs talk about is the lack of space. Our cabins seemed roomy enough to contain all our luggage and items. Even with 3 people per cabin, I never felt cramped. But I did use magnetic hooks on the walls (that were magnetic) to hang my lanyards and hats.
Ask you room steward for extra hangers. Ours wanted to know specifically how many we needed.
You may not need to bring towels on your vacation. Our cruise ship provided towels for each of us to use on the ship as well as for use offshore at various beaches (as long as we brought them back). We always had clean, fresh towels. You will want to return these the night before your debarkation date to avoid long lines.
Do not take the robes home. You will be charged. Leave those in the room.
Your room steward can get your furniture re-arranged if you don't like the set up (even if you requested it in a certain way).
Write down the name and country of every single person who provides you excellent service so that you can mention them in the survey the cruise line will send you after your trip (they may qualify for incentives and rewards). Bring some small bills for tips. Even if you pre-pay for tips, you may want to single out a great employee with a little extra.
