I'm also going Feb. 2, also as a single. I've signed up for the "find travel companion" service. When I booked (recently) the extensions were mandatory! This is a bucket list trip -- my final two continents! I'm 68, and don't know how much longer I can do trips with lots of walking (and getting in and out of the dinghies), so I figured I'd better go now. Hubby says not for him.
Thanks for the shoe advice. I'll bring sandals and sneakers.
