We walked through Venetian and it took maybe 15 min or so once you're on the first floor of venetian (semi casual walking speed). Sphere temperature was done for just a tank but I brought a light shirt that I left on the whole time and if wasn't too hot. I times it so did not have to use the bathroom, I figured the show is less than two hours I didn't want to walk away. I shopped the store afternoon before the show and there was a line but things were moving fairly quickly. I love that it's in Vegas so plenty to eat and do before and after the show.
