Pros:
1. Vegas is a central location, near a major airport, finding a cab is easy (try it at other skating events), parking is free (try it at other skating events)
2. The arena and the hotel are one and the same; I didn't book a room, but I thought the place itself was okay; I can't imagine eating there for days on straight but for a one-off, its convenience is hard to beat
3. It's Vegas! Lots of things to do!
4. The concourse has A LOT of room. There was a long line-up to get autographs with the US skaters, but that hardly made a dent to the space. There is a ton of space to maneuver, even during breaks. I even think the line-ups for the ladies washroom were much shorter than normal, but I'm a guy, so I can't really vouch for that
5. The scheduling was practically perfect. Competition on Friday and Saturday only, with a decent break at reasonable dinner times. Because of the efficient cabbing situation, we could go to dinner on the Strip, and cab back in time for the rest of the competition, with time to spare.
6. Perfect weather
Cons:
1. My expectations of a Vegas skating event were different from the reality. I was envisioning a skating event at the NHL arena, which is in a very nice part of the Strip. The Orleans is not that. I am not a skating purist--I like to combine my skating events with exploring the city. I didn't do as much as I anticipated. But that may be a part of tempering expectations and amending how I plan a future trip to Vegas for a skating event.
2. The arena was freezing to me.
3. Not a ton of staff, so a lot of people were moving down to their seats in the middle of performances. Very distracting.
4. There is nothing to do right outside the arena/hotel. NOTHING.
5. Packing is hard. Weather was actually quite reasonable, but the arena was way too cold. And, yes, smoking is bad.
