Hi kl630, welcome to Cruise-Chat! Congratulations on your up-coming cruise! I hope you enjoy the Emerald as much as we did, she's a beautiful ship. If you get to go to the Crown Grill (extra fee restaurant), be sure to order the Black and Blue onion soup. It is wonderful. Also, check out the Sanctuary. It's a wonderful spot for taking pictures while coming into port.
It really doesn't matter which side you select. It will all depend on how many ships are in port when you get there. Sometimes they'll dock on the port side, sometimes on the starboard side. We've been on both and it really hasn't made any difference. On our Emerald cruise it was about 50/50.
Hope you have a marvelous cruise and enjoy Princess as much as we do. They're our favorite line, so far
