I have never been on the Mof the Seas but twice on the R of the Seas whichever one you pick you can't go wrong, we are doing the M of the Seas in Nov. put the names of the 2 ships in a hat and pick one.
For teens I'd suggest the Mariner. I'm 15 and I went on the Navigator last year. I loved it.
Sovereign of the Seas 2/03
Navigator of the Seas 2/04
Adventure of the Seas 2/05
Serenade of the Seas 2/06
Monarch of the Seas 7/06
Liberty of the Seas 8/07
Majesty of the Seas 5/08
I agree.... for the kids the Mariner is great... much more to do.. the Radiance is a beautiful ship though... lots of glass and very classy...
We are going on the Explorer again... did the Mariner last July... but we Very much enjoyed the Explorer so that is where I chose to take my kids... well they arent really kids anymore.. but just the same...
Dont worry... whichever ship you choose you will enjoy!
