Rock in Rio Festival

First-day festival jitters have been apparent at the Rock in Rio festival in Las Vegas, but perhaps that's to be expected at the inaugural version of a major music festival.

It's been a frustrating opening nevertheless. This is a no-cash, no-credit card event, which, despite much advertising, was news to many. Attendees must acquire an electronic wristband, go to a "Top-Up Station" and load money onto it. Anything you want to buy must be done via wristband swipes. The problem? Of the four stations, only one was working at the start. You couldn't spend your money if you wanted to.

Beers are expensive: $12 for a big can of Corona. Lobster tacos are $17. Unlike Coachella, there's no free water here. As of 6:30 p.m., the Ferris wheel wasn't working. The lush grass that covers the manageably compact grounds is fantastic ... until you realize it's plastic turf.

Rapper Theophilus London's set was solid, but alas, more people were waiting in the line for the free zip-line ride than watching him. The biggest draw so far? Cirque du Soleil. (Psst! They're not that hard to see in Vegas!)
