First, regarding the carmel bars: Agghhhhhh!!!! No caramel pecan bars? As M (youngest, not husband) would say, "NO, NO
and NO!" That alone supports Ben's campaign to return to WDW. Forget the Test Track closure - Ben needs to get back there and you must try the caramel pecan bar! I do appreciate your replacement order. If I were similarly situated, I would absolutely choose the caramel with sea salt. (Did I mention that my sister-in-law is a chocolatier and owns a local chocolate shop? Her caramel with sea salt is amazing - more on that later.)
In the end, I give you a big hug for seeking out my favorite WDW treat in the midst of all this 8th grade trip hoopla!
Back to Ben and his trip planning - how about
MNSSHP?
You have not failed, because it's not over. Here's our plan: Invite each of the boys to celebrate their 21st birthdays in World Showcase - we pay. We'll see if they accept when they get there.

(I've loved World Showcase since the age of 10, but I'm not sure how my parents did that - it certainly was not the photos that my mom made us take wearing hats from each country - yuck.)
