I think these are reasons numbers 1 and 2 for the decline. While the Rio is definitely nicer by a long shot, it simply doesn't matter for those that can't afford it, which I think there are quite a few, and even many of the players that can afford it still don't go because it simply is no longer worth the price to them.
Where would you hold it that would be less expensive? While it is more expensive than past events at the Riviera, it is less expensive than any other league's events that are currently run. Yes, Las Vegas has become more expensive. But our event is still a good value for today's prices in Las Vegas.
