Hi. I share many of your strategies for international travel. My husband and I have taken several Viking cruises since my Bronchiectasis dx. often with extra hotel stays on both ends. Most ships don’t allow microwaves, but I was given an electric pot to boil water. After washing neb, I would use micro bag to put boiling water/ nebs /Aerobikas into. I take at least 3 neb sets and several Aerobikas to rotate. Many hotels had microwaves, so I take advantage when available. I’m also not shy about using a mask in crowded situations or showers that I can’t vent well enough. I carry a LifeStraw water bottle with me and drink bottled spring water. Travel on!!
