Over the years we have cruised on just about all of the major cruise lines. Some have been great and others not so much. So based on our experiences and likes, we have pretty much narrowed our choices to HAL and Princess. Within these we have also narrowed our ship preference, mostly around the class of ships we enjoy.
With Princess we will now only cruise on a Grand or Crown class ship. Our most recent cruise (February) was on a Royal class ship (Regal Princess). We felt very crowded on this ship and was not impressed by the layout.
On HAL we have narrowed our choices to either Vista Class or Signature Class ships, and within these we have our favorite ships. In Vista class it is the Noordam and in Signature class it is Eurodam. In fact Eurodam is our next scheduled cruise next May and are so looking forward to returning to HAL, our overall favorite cruise line.
