Personally I think it's an idea that won't catch on and is at best only practical if you actually live in NYC.

Imagine someone like me having to travel to NYC. Sure it's only 20 minute ride but now look at the costs. Parking there for 3 days is about as much as my mortgage payment somewhere around $42 a day. Add to that a first class ticket for 2 people $300 and don't even think about eating or drinking.
In reality, I could take a stretch limo down for about the same amount if not less and wouldn't have to turn a 2 hour 15 minute trip into 4 plus hours if not more.
Have them pick me up at the front door, drop me off right at the casino and have them waiting there to take me home.

In this economy, I'm not sure where they figure their client base will be. They say the young with disposable incomes.Right now, there is no such thing. I can tell you this, It certainly won't be the little old ladies with blue hair that come down on the bus for $30
