£200 is a lot, and I certainly wouldn't be at all tempted to get a Premium Pass. It will be interesting to see how well they do sell, as in my opinion the Standard Pass is fine for what most people are probably going to want. One thing I will say now though is that new designs for the passes have grown on me, and I wish I was going to have one of the blue ones this season, not my gold one!
Also, I don't think this really deserves as new topic, but the Alton Towers Annual Pass has gone up from £75 to £89, however you can still buy one for £75 online at the moment. I quite like the look of the new Towers pass as well, which can be seen here
