Though I don't have any information in regards to the Grand Princess possible refurbishment. I am able to share with you that an acquaintance of mine cruised on it a couple of years ago and loved it! I often find this 'cruise review' site helpful
when deciding on which ship would work best for our interest at the time. It appears that the Grand Princess is included.
This will be our first cruise on the Sapphire Princess...we are sure looking forward to it.
Regardless of where or which cruise line you choose to relax with...ENJOY!
