The park have been raising ticket prices by way above inflation rates for some time, now. They tend to go up between 8 and 10% per year. I think they'll continue doing this until they find the sweet spot, and gate figures start to drop significantly. Until then, it will continue to rise.
As for Fastrack, as I briefly stated, I have some concerns over the new packages.
Air, Nemesis, Nemesis Sub-Terra.
Both Air and Nemesis have throughputs of around 1,100 to 1,300 per hour. Sub Terra is literally, half those. I worry that the effect of fastrack on Sub Terra. The ride already has one of the slowest moving queues in the whole park... it should only be on the gold and platinum options, if you ask me.
Rita, Th13teen, Oblivion
Again - throughput on Th13teen and Oblivion is 1,200+. Rita barely scrapes 900 to 1,000. I worry for the effect of this on Rita's queue, when it, like Sub Terra, moves very slowly.
Family Package
I hope this is extremely limited in sales. Sonic Spinball does NOT need fastrack and I know for a fact that the ride staff on it detest the bunged up entrance with people for disabled and fastrack...
