Hi Woodranch, we stayed in a junior suite last month on the Mariner of the Seas. From what I understand, they are identical. There were four of us also, and there was more than enough room. The junior suite is quite a bit bigger than a regular balcony room. The bathroom is large with a tub/shower combination. Very new, shiny and bright. There is a large walk-in closet with shelves that are built into the wall. More than enough room to store our 4 suitcases. The room itself has a king-size bed that we asked to have separated into two twin beds for the kids. Then there is a queen-size pull out sofa-bed that we slept on. There is also a chaise lounge in the room to sit on. The most important thing (aside from the larger balcony) was the fact that when the sofa was pulled out into a bed at night, there was still enough room to walk around. We were never cramped, it was great!
