We are so amazed on how big this Royal Caribbean Mariner of the Seas. It is a 15-decker cruise ship with 4 pools, 6 whirlpools, casino, spa, gym, restaurants, cafe, promenade, rock-climbing wall, mini-golf course, basketball court, jogging and in-line skating tracks and theater. Wow! That's huge ... but did it give us more memorable experience compared to Superstar Gemini?
