I have been traveling solo, mostly in my RV since my husband passed eight years ago. I wanted to branch out and found vacationstogo.com they have a site that list cruises for solo travelers. This is different from hosted single travel. The cruise single supplements range from 0% to the highest I have seen 40%. The rooms, length of days and cruises differ. I used this site many times when my husband was alive because we loved to cruise. I am currently looking at a 15 day cruise going to to the Falkland islands. Happy traveling
