I have provided a star system with five being the highest as part of this writeup.
After having sailed 160+ days on Crystal Serenity on our most recent adventure, we chose this 14 day Dover Round Trip cruise because of its itinerary and, in particular, because of its stop at Liverpool. This is a major birthday milestone year for me and although my actual birthday was not on this cruise, we selected this cruise because of my love of The Beatles.
We have stayed in many of the room categories on Crystal Serenity and our favorite is this category as it provide additional space and butler services. We don't feel as if we need anything larger than this. The good news is that whatever category you select, you will receive the same services throughout the ship.
