Europe cruise option

Need all the recs/opinions!

I’ve always been a huge cruise girly and I got my partner into cruising last year when I took him on his first one to the Bahamas (precious).

I really think taking one for our honeymoon is the best bang for our buck and a way to see more places.

We’re debating between Greece/med, British isles, and north Europe (Denmark, Norway, Iceland). Has anyone been on something similar and can provide feedback? The biggest note I’ve gotten is that a med cruise can be overwhelming because it’s typically a port every single day so it can be very “travel” and less “relax.”

Open for all suggestions!:)
