Definitely the Boardwalk. You will be able to walk to the food and wine festival, and the kids will love the deluxe resort. We spent a week at port Orleans, and the kids loved it, but we had a car. Last year we stayed at the Poly and were hooked on the deluxe. The extra space, private balconies, and pools are great.
There was a storm in our home state last year, so we had to spend one extra night in Disney. They offered us a deal at Caribbean beach. We had already returned the rental car, and busing was a nightmare! The resort is huge, and although we were only there a day, we could not figure out how their bus stops worked. They didn't seem to always stop in the same place. It was very confusing. We would never stay there without a car.
Have a great trip!
