LOL oh my, been there done that, and feel the exact same. You did forget to list the pool party til midnight prior to the 8am elimination game though.
I can't tell you the number of times between then and now that I've left the park grumbling that not a dang player here REALLY REALLY wants to play the game, absent the swag and show and entitlement of it all.
And yes it continues right into college, high school, summer leagues, etc.
"To me it goes back to when we were younger playing travel. Most families went to the tournament looking for what they could do. We went to the tournament to play baseball. I despised the parents that allowed their kid to go to the beach during a world series and get sunburned and not be able to play. You are there for baseball not vacation. But I knew I was in the minority. We had a family that wanted to miss a pool play game at Disney for Elite 32 to go to the theme park. I voted if they missed that game the kid was not allowed to play the rest of the tournament, but I was outvoted. "
