Various questions about what to do while my daughter skis????

My wife and I are taking my daughter up on the 25th for her first time. She'll take a lesson, and my wife and I will hang out in the lodge (too pricy for me to ski as well).

Anyway, I haven't been to Stevens in almost 30 years.

1. What's a good lodge to hang out in for the day? I suspect we'll be using our phones/tablets most of the time. Are there places to plug in our chargers?
2. Any decent food or should we bring our own? I don't want to spend a lot, but I know the food won't be cheap.
3. We have a parking reservation and are aiming to be there about 8:00 AM. We live in Lynnwood, is 90 minutes an appropriate drive time?
4. Is there anything for us to do while we wait for our daughter? Driving to Leavenworth might be an option since it's only 40 minutes away.Anything else we can do while at the pass?
5. We have AT&T phones, is there cell coverage up there?

Thanks!
