Are you my boss??? lol....
Both, We arrive on Friday and my obligations at the meeting don't start until Sunday evening with a reception off property. I have meeting activities Monday and Tuesday during the day, but will be in the park Monday night. I may rope-drop Monday before my meeting activities and catch a ride or two. I have a MK so it's a no brainer for me.
Yes, people bring their families, but to my knowledge it's still "school days" Monday-Thursday that week for every district in the nation which could limit some traffic mid-week.
Regardless of crowds, it's a beautiful time to be there and thankful for the chance to stay at the GCH at such a great rate and not have to use points and do good work in the same week!
