New to the board and to cruising - I hope you'll forgive my newbieness! I'm looking at the possibility of cruising on the Celebrity Infinity from Valparaiso to Buenos Aires (going through the Strait of Magellan to Punta Arenas, back to Ushuaia and around Cape Horn) form late March into early April. I know that conditions can be unpredictable, but I'm trying to get a sense of how rough of a ride to likely expect. I tend to get seasick very easily without medication, but I've been mostly fine on boats with Dramamine (and on large cruise ships the motion hasn't bothered me much -- I took Dramamine during one rough sea day in the Mediterranean on a large cruise ship this year and on a recent Caribbean cruise I didn't take any medicine and I was fine). I have very young kids (ages 5 and 2) and they have been fine on large cruise ships, but both got seasick within an hour on a catamaran in the Mediterranean on a pretty calm sea day. I'm trying to get a sense of what to expect on a boat the size of the Infinity. I read a review on a blog about a trip in February that sounded like it encountered very rough seas. From what I've read, winds should be a bit less in late March / early April, but I don't know whether that means a smoother ride. Are we very likely to hit seas rough enough to be knocking things off of shelves? If that is likely, is it likely to be that way for days at a time or hours or what? Has anyone done it and been completely miserable (or who expected to be miserable and was totally fine)? Is it rocking and rolling the whole time?
I completely understand that it is impossible to predict sea conditions, I'm just hoping that someone here is familiar enough with it to help me make a more educated decision rather than winging it thinking "It'll probably be fine". I'm alternatively considering the same ship from Buenos Aires to Antarctica, which goes down past Cape Horn to Paradise Bay, the Gerlache Strait, and Elephant Island. I've posted separately on the Antarctica forum about that and I recognize that both of these cruises might be poor choices for us given sea sickness concerns (I'm open to being convinced not to pursue this course at all), but like I said I am trying to make an educated decision and I include that alternative in case anyone has done both and can offer a comparison.
I appreciate any and all advice / wisdom.
