I visited Hollywood during Fan Fest Nights and got to do all the mini games and Bowser Jr. without any wait. Plus it was nighttime in California instead of daytime in Florida, so it was actually pleasant to be outside. At Epic I didn't even attempt to play the games because of the crowds and heat. But those extra rides in Orlando can't be argued with. And I bet if I went in the middle of the day in the summer, the land at USH would get pretty unpleasant too.
My main takeaway now is that both coasts need more Nintendo ASAP.
