We are going to SW for the first time but this will be our 4th time to WDW. So I am used to the Florida heat a little. Are most of the attractions at SW in the full sun or are there a lot of covered areas? Are the shows that are covered still very hot? We have young children and will most likely go from 9-2. Is this enough time to do most of the age appropriate exhibits and maybe the dolphin show? What shows are a must see for 3-6 year old girls? Is SW a "hot" park or is there plenty of relief from the heat? We are going most likely June 11. TIA!
