I'm Cas. I write the blog here at Cruisello, from the Netherlands.
Most of what I do is compare cruise deals and figure out which ones are genuinely good. I also write destination guides and try to include the stuff that's hard to find elsewhere, like whether a port is walkable or if you really need to book an excursion.
I spend a lot of time watching prices move. Cruise pricing is weirdly dynamic, and catching a drop at the right moment can save you hundreds. That's probably the part of the job I find most interesting, honestly.
If you've read something on this blog, it was almost certainly me.
