Angi, on page 2 of the thread I ran some rough numbers for why I suspect the impact on crowds that week will be modest at best. Having said that, Friday at MK may well be the exception. (Thankfully, I'm booked all day at DAK that day.)
Also planning to hit the After Hours event that evening (maybe we can say hi), but my gut says that folks who are there for football are likely not to be the same ones who will shell out an extra hundred bucks for a few extra hours in the park.
Like you, I'm also planning to wait until I see the weather forecast before plunking down my money, but I'm not concerned about a sellout. We'll know more once we see what the first one is like the preceding Friday.
