Long time lurker here. Our family (hubby, 14 yo son & 5 yo daugther & me) have visited WDW bunches of times, but are new to a LOT of things this year. We closed on a DVC about 2 mo. ago, ordered our 1st APs last week, and are doing DDP for the first time in Aug.
I feel like we're walking into a minefield of ways to look like jerks at WDW

We so desperately want to avoid being the self-important ignoramuses that make you fine CMs hate your jobs.
Now that we've financially committed ourselves to 1-2 trips a year, please give us some good tips on how NOT to be passholes (and how to help first-timers we bring with us to do the same)!
