Andrew,
I met your dad this morning on the way to the comfort station. Imagine his surprise when I greeted him by name as he walked off his site.
He is a very nice man. Sounds like you have a lot of family fun planned. We talked popups and he told me the unfortunate circumstances of how he came to have this popup. He also said ya'll make fun of how long he takes to get ready (or something like that).
Travel safely, have fun, and treasure those family multigenerational vacations together.
