Well, we haven't tried them all, but since we're heading down on the 18th, we've been doing all sorts of reading. We're planning on hitting the following CS's if they fit into our touring plans.....
Sunshine Seasons at The Land in Epcot
Pepper Market (We're staying at CSR)
Tommorrowland Noodle Station
Flame Tree BBQ
Plus a whole bunch of places in World Showcase. We're definitely planning on using the CS credits to eat things out of the ordinary for us!!
When we went two years ago, we didn't do a "good job" of maximizing our snack credits. This time, we plan on saving a bunch for FWF, and using many for better dessert type items from Main St. Bakery, etc. We love Mickey Bars, bottled water, and popcorn, but there are soooooo many better ways to spend the credits!!
