Happy Anniversary Wishes from us too. Our actual anniversary is January 2 but we celebrated it a month early last year at Disney and with our anniversary buttons we received more well wishes and free perks at meals than we've ever received before.
Splash Mountain in Magic Kingdom and Kali River Rapids in Animal Kingdom are great chances to cool off. Use Fast Pass for them. There are also misting stations - one is near Test Track in Epcot.
Costco wants to build a new store in our neighborhood - just 1.5 miles away. If all goes through, in another few years I'll finally have one near by.
