Welp - it was an adventure. When you plan so far in advance, there isn't much you can do to adjust around weather. Just cope.
Saturday we rode TRON at 11 pm, front row. ChatGPT tells me that wind chill after the launch was -1 degrees.
Sunday at Epcot almost was worse even though it was sunny. Looks like they had some pipes burst, places like the misters?
We made the best of it. Got a front row seat for fireworks near Italy at 8:59; not a soul in sight.
