We’ve done a couple of “big ship” cruises and we decided they weren’t for us; too many people basically. We decided to give the Royal Clipper a try. For us, this turned out to be a good experience.
If you want a casino, cabaret shows, dressing for dinner and so on then the Clippers probably won’t be your thing. If you prefer a more informal experience then yes!
It’s probably not best suited to those with significant mobility issues - no lifts, steep stairs, heavy doors and tendering at most ports will make things hard for you. That doesn’t mean you need to be mega fit but just reasonably mobile.
