Ocho Rios-Dunns River Falls, Cozumel-Chankanaab Park or Tulhum/Xel-ha excursion,Grand Cayman-Sting Ray City, and Princess Cays-Beach day. If you want tons of posts for your ports, you can use the "Find" feature in the upper left hand corner. Type in your ports and it will pull up all the posts made about them. You might find something that really interests you. Hope you enjoy Princess as much as we do, they're our favorite line, so far. The Ruby is brand new, and she's a beauty. We sailed on the Emerald last year.
Here's a link to some pictures from the Emerald if you're interested. If you go to the Crown Grill (extra fee restaruant) try the Black and Blue Onion Soup-awesome! Check out the International Cafe on the Plaza (I believe) deck. They have some free items for lunch and breakfast, plus they have gelato 3 scoops for $1.50 that was fantastic. Best wishes for a wonderful cruise!
