Congrats on your cruise!
We had a JS
when we cruised on Enchantment this past June. I would think the extra room that it provides would be great with your kids.
One thing though, our cabin was close to the elevators and right under where the transition area from the Solarium to the outdoor pool area is on the deck above. nce or twice a day we could here the crew rolling something through that passage way and it sounded like a herd of elephants. My reccomendation would be get a little more toward the rear of the ship to avoid this. Other than that, we loved it and we probably would not hesitate to book that cabin again.
Here is 3 or 4 pics of our Enchantment JS
Hope that helps.
