We've been cruising for over 10 years now, and my worst swelling experience was last year on the Magic. We were on the first NYC-Bahamas-WDW 8-night cruise. About halfway through the cruise my ankles swelled a LOT (yes, I had cankles! ), and because I have high blood pressure it worried me a little. I take my BP medication religiously, and I take ibuprophen several times a week with no swelling, so this was definitely a reaction to something on the cruise. DH was sick on the cruise and we had to visit the medical area a few times; the doctor checked my BP for me so at least I knew it wasn't high. At bedtime I put an extra pillow beneath my ankles, to reduce swelling, and I also would run cold water in the tub and soak my feet for a little while. I think I'll ask my own doctor for advice, before our next cruise. P.S. I don't remember swelling while on any other type of vacation; I think it has a lot to do with the sodium levels in the food on the ship.
