more photos on the ship....  
One of the coolest places on the ship is this little, out-of-the-way area. You can check the computer to follow the ship's progress. And, you can stand in front of this heat-sensing camera (on left). It shows your body heat on a big screen. Hard to explain what the attraction is, but we certainly enjoyed playing with it!
One day a couple of the staff gave a demo on how they dress like clowns and a little bit of the history. This was done in the Royal Promenade area. (below)
  One reason the ship is called Explorer of the Seas is that there is an actual oceanic research lab on the ship. They offer tours of part of the lab. (below)
After a couple of days, we realized that everyday they change out part of the floor in the elevator. (below)
