We're heading to DL next weekend and it looks like highs are expected to be in the 60s. I'm not sure what to pack! I know we'll need something warmer (jackets/sweatshirts) in the evenings, but is it warm enough for shorts during the day??? I'm coming from Seattle, where it's been 40 for a few months now, so I can't even comprehend what 65 and sunny is!
