Last couple of nights were downright cold,today I went to Epcot and it was low 70s during the day and in the 60-65 range at night,much warmer than its been lately but it still cools down enough at night to need something more than a t shirt.I had on shorts and a shirt and hoodie all day,never really felt hot with the shirt and hoodie and at night I was real comfy,tonight there was little to no wind so that also helped it not feel too cool.As far as crowds,it was definitely not crowded,not low crowds by any means but the crowds really start arriving this weekend.
