There are a number of options available including the Leaping Libations pool bar--sandwiches, salads, etc., The Screen Door (general store on the Boardwalk), and I seem to recall back quite a number of pages that someone did indicate Boardwalk To Go was up and running, but that may have been for a busy weekend, i.e., Memorial Day or maybe just weekends. Short walks from BWI you can hit up BC Marketplace and Ale & Compass Marketplace at YC. Swan & Dolphin each have a couple of grab and go places as well as Picabu at Dolphin which is a fast food restaurant with pizza, tacos, grab and go sandwiches, etc. Loads of choices for teens/tween.
