The pumpkin dip sounds good. I was thinking a Buffalo Chicken Wing Dip. You can make it in your crock pot (any recipe that you see calls for the oven but you can make it a crock pot and it's just as amazing), and in the crock pot it'll stay warm as long as you need it to. This is recipe I use:
1 1/2 lbs chicken breasts, cooked and shredded
1 (12 ounce) bottle hot sauce (use whole bottle or just half, if desired)
2 (8 ounce) packages cream cheese, softened
1 (16 ounce) bottle bleu cheese salad dressing (or can use ranch or 8 oz blue cheese and ranch)
2/3 cup chopped celery
3 cups shredded cheddar cheese or monterey jack and cheddar cheese blend
Chips or crackers to dip
Directions
Bake chicken 350 for 1.15min
1. Preaheat oven top 350.
2. In a large bowl, mix shredded chicken, celery and cheese.
3. In a saucepan over med-low heat, combine cream cheese and salad dressing and stir until smooth. Stir in bottle of hot sauce ( don't have to use entire bottle if you want it milder). Pour heated mixture into bowl with chicken mixture. Stir to mix well.
4. Pour everything into Crockpot, and heat high for 2 or so hours then turn down the heat and serve!

4. Pour into a 13" x 9" baking pan. Bake uncovered for 40 minutes or until bubbly----make sure top doesn't get browned. Let stand for 10 minutes.
Serve warm OR cold-----tastes best warm--- with celery or other veggies, taco chips and crackers.
