We are going to WDW in 9 days from WI so I am in the same boat as you. We will be at WDW for 10 days so I am packing enough tshirts, socks, undies for everyday. 5 pairs of shorts, 5 pairs of long pants, 5 sweatshirts and 3 longsleeve shirts for each dd. I'm just going to cover all the bases and plan on sending the dirties to the laundry to be cleaned half way through the trip.
We will also have our winter coats with us since when we leave in the early morning it will be like 20 here. Hopefully we won't need those!
I looked at our last trip pics and saw that the night we went to
MVMCP we all were wearing shorts and tshirts at 10pm at night. So who knows....
Preparing for whichever way the wind blows....
