Kimbra, I am SO jealous! I am a Royal Carrib Crown and Anchor member and have been on 5 cruises and am hooked! OMG!
Well, let's see... I haven't been on one since my AN diagnosis, but... cruise ships have stabilizers on the keels, thus, if you run into rough waters, they help to minimize the movement. I remember being on an 80,000 ton ship back in 1998. Our ship was sandwiched between 2 hurricanes (I think it was Bertha and Earl). Anyway, we did run into some rough waters off of Grand Caymen so it was a bit tipsy but other than that, never had an issue.
I also know that depending on which deck you are on, the closer to the water level, the less likely to feel "sway". Example... many of the newer ship's spa are up on higher decks (ie: 9th, 10th, 11th deck). The higher on the deck count you go, you will feel the sway, but if you are on the main decks near water level, you really shouldn't sway too bad.
I would suggest bringing along Dramamine or Antivert or vestibular therapy exercises to help the cause... just in case.
BTW, I want pics of you all during the "muster drill!"
Jealous is an understatement! Send me a postcard!
