I'm not particularly a fan of cruises. Thus, this cruise does not interest me.
I have traveled on a rather large river boat down the Nile for, I think, a mere five days. All in all, I truly, truly liked this adventure and had hoped that it would have been for seven to ten days vs the five.
I've traveled to six of our seven continents and have lived in two: Australia and North America, so that component has already been met.
If my health holds up, I would like to plan my own adventure around the world over a six month period though, returning to some of my favorite countries and exploring a few new ones. But, if this happens, it'll probably be three or four years from now when COVID has tremendously subsided.
