If you can give us an idea of what type of vacation you are looking for (romantic, relaxing, fun, etc.), maybe we can make some specific suggestions.
My DH and I are also going to WDW in November for a belated 1st anniversary trip. We do not tend to eat at the pricier restaurants or stay at the expensive resorts, but we always have a great time.
For a romantic evening, you could go on an Illuminations Fireworks Cruise ($75+, I believe) or spend an evening relaxing in a hammock under the stars on the beach of your resort (CBR is great for this).
Make sure you take the time for "adult" things... go to Pleasure Island, or if your budget allows, Cirque du Soleil would be fantastic.
HTH!
