We are going from the 11-18, but went two years ago during Pop Warner and it was fine, just some cheerleaders occasionally practicing out on the lawn (we stayed at POR). It did not bother us at all. The weather that year was very pleasant. During the day we wore jeans and sweatshirts with t-shirts underneath, and by afternoon you could be just in a T-shirt. Needed a sweatshirt for nighttime. DH wore shorts, but he's like that! We're just a few hours away in S. Ga, so our weather is almost the same and I can tell you December is very unpredictable. You can have one day VERY warm, the next day freezing so bring it all and be prepared. I would much rather have the weather a bit colder than burning hot like a summer trip. Oh, and DH and DS did swim everyday in the heated pool, but it was a bit cold for me (not the water, just the outside air).
