There is no doubt that the Eclipse Tours cruise is too expensive for most people. On the other hand, the Atlas World Navigator has room for fewer than 200 passengers compared to over 3600 for the Discovery Princess , so ET doesn’t need to attract most people.
For me, the 2024 eclipse will likely be my only opportunity to see a totality. I booked on the World Navigator back in February because I didn’t want to take any chances. In particular, I wanted a cruise that didn’t just happen to be in the path of the eclipse, but was truly centered on that event. In particular, it represented (outside of chartering a jet) the best chance of experiencing the event under clear skies as this is a chartered cruise run by eclipse aficionados who will “direct” the captain to navigate to a cloudless area if at all practical.
