Hi, Cindy!
Everyone staying in your room must be on the same package, so your teens will also have the meal credits. Why don't you let them pick a meal or two, that way they are more likely to show up for the reservation? Some locations they might like: ESPN Club on the Boardwalk, Rainforest Cafe at either Downtown Disney or Animal Kingdom, Teppan Edo in the Japan pavilion in Epcot (where they cook your meal right in front of you!), or Whispering Canyon at Wilderness Lodge.

Another idea is that since your credits are all pooled together, you and your hubby can enjoy some Signature Dining locations that require 2 table service credits - imagine a romantic dinner for 2! You might enjoy Yachtsman Steakhouse at the Yacht Club Resort, California Grill at the Contemporary, or Le Cellier Steakhouse in the Canada Pavilion in Epcot. If your teens don't want their credits, you can enjoy them!
Each of your Key to the World cards will have all of your Dining Credits on them, so if your teens go off by themselves, they can just present their cards to cover their meals. They have to eat sometime, so make sure they know what they are entitled to.
I have no doubt that you will use up all the meal credits. I hope they slow down enough to join you for a nice meal or two. Good luck!
