Have you been on Royal Caribbean's "Mariner of the Seas"?

I am booking a cruise with Mariner and I don't know what room is better, oceanview or interior.
I was told by a few people to book an interior room in the Promenade.
Have you roomed in the Promenade and if so, is it loud at night?
I don't mind a little noise but not so much that I can't sleep.
Also, what are the best activities onboard?

Thanks
Typically there are four classes of cabins on a ship. Interior (no windows), ocean view (has a window), balcony (has a door to a private balcony - usually the door is part of a floor to ceiling window) and suites. However, the Voyager class and the Freedom class (the Mariner is part of the Voyager class) has a fifth unique category which is a promenade view cabin. This is an interior cabin with a window overlooking the Royal Promenade.

I have been on the Navigator (Voyager class) in a balcony and the Freedom (Freedom class) in a suite, but have not been in a promenade view cabin yet. I am booked on the Mariner in June 2009 and have booked a promenade view cabin. My understanding is that these cabins are not noisy. There is a window, but it is an interior window. The lighting in the Royal Promenade is adjusted based on the time of day (brighter during the day, less bright at night). So your window will allow light into your cabin.

This is an ocean view cabin ...

This is the Royal Promenade on the Liberty of the Seas ...

These two are the Royal Promenade from the Navigator of the Seas ...

You should be aware that the windows are not one way glass, so you might want to close the curtains while you are dressing.

The Mariner has several choices for activities, including two main pools, a rock climbing wall, skating (both ice and inline) miniature golf ...
