Denise -- oh my gosh -- just saw your Gamma Phi jacket. I'm also a Gamma Phi! And if you saw a picture of me (my computer illiteracy prevents me from posting one) you would see we have similarities.
Sounds like the kids are having a great time, even though one of them has sensory issues. My oldest had mild problems, and went through a year of therapy, so I can sympathize.
Here's PD that you continue to have a great trip!
