We have enjoyed the Sun so much we sailed her twice. Both 10 day fall Caribbean itineraries. We also sailed the Dawn the year before which is in the same class. We really enjoy the small ship feel. Too bad that Princess is not using the Sun anymore for the 10 day Caribbean itineraries in the fall. The new Emerald will replace it. So, we will probably sail her in the fall. She is a grand class ship, similar to the Crown, Grand, and Caribbean Princess. We have also sailed the Grand and found it exciting as well. We liked the sun class ships as the public areas were not as crowded. We never had a problem with dining or any entertainment venues. Although, being a smaller ship, it can only offer so much. I totally agree with joyceh, the walk around promenade deck is great. It would be great for viewing opportunites in Alaska. But, it's all in what you want. We have always had a great time. Hey, we're on vacation. What can be so bad about that, right? Either way, I know you'll enjoy your cruise.
