I went on a cruise 2 years ago, but that was in the opposite direction. We went to Mexico and Jamaica.
I have been sorta dxed for 6 years, just positive last year. So I just had the surgery on the 14th. But anyway my point was, lol, that as long as I did not do too much walking I was ok. But that is hard to do on a huge ship and when you go on an excursion. I think the climate change was pretty tough at first tho. So I hope you will have time to adjust to it. I was really really scared to go too. But it was such an awesome experience for me and my kids. And thank goodness everything went ok.
I am glad you get to lower your pred. That stuff is horror, but so necessary. Glad to hear you are feeling better!!!
Hope it all works out.
