We stayed at the Hyatt (hawk team hotel, yes we were aware when we booked, we stayed there 2 years ago and liked the location and pools) and didn’t really encounter much. Some intelligent/friendly conversations and of course the few douchebags, but for the most part we just avoided and ignored each other as fanbases from what I could tell.
We had a great experience with an Iowa staff member and their fam by the more resort style pool on a Tuesday. But Wednesday morning all we could hear by the other pool was a loud vapid hawk- not sure if she was a coaches wife or players mom, but had no awareness of her surroundings trashing Iowa State fans around the area. Like a conversation you should have in your room, not loudly in a public place.
