Not first time cruisers, but this was our first transatlantic crossing. We were not sure what to expect. We had read so many reviews and scoured the internet for information. Here's the BIG PICTURE summary:
Fantastic cruise that was not boring or too long by any stretch of the imagination. Mariner of the Seas was a great ship with fantastic service. We don't think we could ever take a cruise shorter than 7 days from this point forward.
Activities were available all day/evening if you wanted or you could be lazy and lounge around. Either way, there was something for everyone.
Cabin is an inside-out. Meaning it is a standard inside cabin with no window on the outside of the ship. Located close to the aft, port corner of the ship. It follows a row of balcony cabins towards the back. It is very quiet and small, but functional. No issues at all.
