At this point, unless you are looking at the forecast for this weekend, I'll give you the advice I give anyone else looking at the forecast for FL (or most anywhere else for that matter)
Consult your Magic 8 Ball.
Or a Dart Board
Either one stand as much a chance as being right
It will not rain all day every day. I am not sure FL has ever had day after day of all day rain. Has it ever rained for say, 3 solid days? I'm not even sure
Some rain every day, yep. That it will do. You can be almost count on somewhere, in WDW, it will rain every day, at some point.
But, I think the bottom line is, unless you are going to change your trip, you poncho up (or in our case umbrella up) and go. You don't change plans, outside of maybe replan a water park day.
