OP here -
Thanks for all the input!
We are going Jan 7-12, and I used the Accuweather App to check on the Orlando forecast. I'll pull up a local news station and check that as well.
We vacation in Orlando during the summer normally, and we are very prepared for the Florida thunderstorms that roll in. But we've never been to FL in January, and I was surprised to see a day calling for rain all day! We only have a few days there, so I am getting a little panic-y (you should see me checking the local PA forecast to make sure we can get off the runway!).
We have umbrellas and ponchos and don't mind getting a little wet. But I would be very disappointed if we couldn't get on some of the attractions our whole visit. We have one-park-per-day passes, so two days at each park. If we miss anything those days - we won't see it.
Hopefully, we'll have good (enough) weather to enjoy the majority of things. And I'll watch the local forecast and try to plan the rainiest days to be in the Studios.
