You live in Louisiana, yes? And Angie is in TN. Similar hot weather to FL, right?
Now try coming from a different sort of weather place and trying to figure it out.
40 degrees in Seattle DH is still wearing shorts. 40 in Orlando and he's nearly in tears from the bone chilling cold especially at Epcot.
There's a feeling of morning at WDW during colder times that just doesn't hit our area often. It's so unique that ds and I comment on it when we feel it. So no, we don't dress the same or based solely on temperatures as when we are at home. Because it just doesn't feel the same.
And I'm writing while DH is driving through melting snow, it's in the high 30s, and I'm in Capri yoga leggings, a running shirt, and a sweatshirt and I'm fine. But 40 in Orlando I'm wearing way more than that!
There's also the difference of how long one is out in the weather at wdw vs at home.
