We were at the parks the first week in December last year. I wore capris or jeans and t-shirts and had a sweatshirt for the evening. One day it was VERY hot, I left to go change into shorts by the afternoon. But, it did seem to cool down a lot when it got dark.
I didn't think we would be able to enjoy the pool during our stay, and it was our first time staying at the DLH. However, hubby was able to take the kiddos to the pool a couple of times while I was out shopping!
