Think Ale and Compass at the Yacht Club would be a good place for your to consider for either breakfast, lunch, or dinner. Maybe not the 'least expensive table service meal in a park or resort', I didn't compare all the pricing, but it's 'relatively' easy on the pocketbook, a very nice restaurant in a beautiful resort, plus close to Boardwalk, Skyliner, and International Gateway, too.
Wherever you go, Squishie, sure hope you have a magical time!
