I think that implementing the new guest policy next year will have a substantial affect on the crowding issue. Some will have no changed attendance behavior because they'll get AU cards, but I think this will be in the low single digits percentagewise. I also think that few will buy guest passes when compared to the number of guests that will no longer be eligible for free admittance. Also, consider that it's not just the guests that will disappear - I suspect that in many cases, people that are traveling with 1 or 2 other people on the same trip and are now going to the CL as a group will have none of them go once the new rules are in place, as the Platinum cardholder is unlikely to go in by themselves and leave their travel companions in the terminal.
