Two things:
1. A logistics question. So let's say I get up, walk on over to the food court, get the adults in my party their coffee and bring it back to the room. Drink, stop for another cup on our way to the buses. Is it worth bringing the mugs to the park with us? Ideally, I'd get a third cup IN the park, but they won't put it in the mug, right? The idea of reusable mugs that I can't use where I'm spending the majority of my time just doesn't make sense to me.
2. Our sons have the same name! Do you pronounce an A or E sound at the beginning?
