I'm the same as your husband.
I can't handle crowds and the random stopping etc. Drives me crazy!
We handle my moodiness by doing a few different things.
-duck into an air conditioned theatre/show attraction ie. HOP, COP, Ellen
-find a quiet corner and just chill with a drink for a few minutes. We really like to hang out in The Land pavilion at a corner table in Sunshine Seasons.
-take a mid day break most days
-last trip my crazy kid put some glitter in a small tube and the first time I got grumpy she sprinkled me with Pixie Dust. Who can stay mad with your adult child throwing Pixie dust at you to brighten your mood - but, I guess for some that could go either way. You may be taking your life in your hands. Sprinkle Pixie Dust with care.
And before anyone makes a comment, no one else was afffected by her pixie dust. It was a very minimal amount and it only landed on me. It was more for show and to make me laugh. It worked.
