My bgs don't do AIRPORTS!

Just back from Eurodisney. All went well, no probs with food, bg pretty good the whole time. It all went out the window when we hit the airport on the way home. Everything that could go wrong did and my bgs went crazy. The thing is, it has taken me three days to recover and manage to keep bg within range. I never want to see another airport again as long as I live. Glad to be home. Missed you all,
