Wouldn't you know it, on my very first excursion at the Mendelhall Glacier in Juneau, I broke my ankle! But don't worry about me, I didn't miss one buffet, one show or any of my other excursions. If anyone has any questions about Alaksa, what to pack, weather, or the Radiance of the Seas, just ask. I will be more than happy to answer any questions. In a nutshell, you should pack: Sweatshirts, a windbreaker, sneakers, jeans. Don't bother packing shorts or a bathing suit - the only people in the hot tubs or pools were children. Of course some dressy clothes for the two formal nights on the ship but other than that, you can go to dinner in jeans on all other nights. Lots and lots of film or batteries for your camera. You don't really need binoculars, most excursions that view wildlife lend you binoculars. Please let me know if you have any questions at all. Hope this info is helpful.
