Deck 14 is still mainly cabins. The aft end is closed off and joins both sides, though there's no access from one side to the other. Mid ship is the "card room". Didn't check it out.
At the forward of the ship is the kids' area. This is an amazing area for children. There are 9 or 10 rooms, ranging from Workshop to a science lab, to a theater, to the kid club rooms. On the Freedom ships, they share the deck space with 'the public' near Johnny Rockets. The artist sketch of the Oasis shows the kids' area having the front deck area to themselves, however, photos of the Oasis (and my photos of the Allure) show this not to be the case. It appears you can access the front deck by going down the long cabin hallway on either side of the ship, and there's doors that open to the front.
The kids' area on the Allure kind of made me jealous, LOL. I wanted to play and explore. Indeed, they do offer some adult classes, but well...you have to pay extra and try to schedule them into your already busy day.

This looks like a great site for "touring" other ships as well. It organzies the pictures more by "theme" (ie: kids' stuff) than by deck
