I don't have the energy this, but a few quick things.
- As Sven20 said, nobody knows what the numbers mean for Six Flags. It's been about a year since they had a quarter that you could reasonably compare to a previous year. Q4 will always be up because they seem to add a winter event to a new park every year so they have way more operating dates year over year. Q1 was up because Magic Mountain added tons of operating dates compared to last year. Q2 was up because for the last 2 weeks of Q2 they had 5 more parks which ends up giving them about 70 more operating dates. Q3, Q4, Q1 next year and Q2 next year will be up no matter what because they'll have these parks driving pass sales and giving them additional operating dates when compared to the previous year. Q4 will also have new operating dates from Frontier City (through December), Darien Lake (in October) and Holiday in the Park at Six Flags Great America. ...tl;dr: No sh*t Six Flags is up.
- Enthusiasts love to pretend that **insert thing they don't like about a park / chain here** explains everything bad that happens to them because they want it to be true. That said, nothing has changed in that regard for about a decade. It's totally nonsensical to attribute this sudden drop to something that's remained constant for years.
- Indications are that the biggest drops seem to be at Cedar Point and Kings Island, two parks that have built huge, awesome coasters in the last 2 years. There goes your " if you build it they will come" argument. Cedar Point built the ride that people have been clamoring for for years and they certainly did not come. Kings Dominion built their most amazing thrill ride in a decade and they weren't mentioned as a big success story with that either (though we don't know the numbers park by park so we're just going by what we could discern from the conference call).
