We have been at SW when it has rained-lots of times. Only thing that closes are the shows in stadium and coasters.
When it rains....head to Turtle Trek, Antarctica for the penquins or Wild Arctic depending on which side of the park you are on. All are continuous. Take your time in the aquariums and shark encounter
Take a long lunch at Voyagers or at the Shark restaurant. .
Shop in all the connecting stores in the Waterfront area.
