Even though it's not a hub, prepare to do a lot of walking because Las Vegas is a popular destination. You must also take train between the gate terminals and checkin/baggage claim. You realise the amount of peak traffic that the airport gets when you see so many carousels at baggage claim.
If you still haven't gotten the gambling out of your system, there are slot machines waiting for you at the terminals in addition to the food concessions and stores. The airport has gone through major renovations the past two years and has expanded with a new terminal. Lots of open spaces that can accommodate crowds that arrive for the conventions. Best feature is the free wifi and it doesn't seem to be censored since it's Vegas.
