The O2 sensor is mounted in the exhaust manifold to monitor how much unburned oxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).
There is no other way to say it: Legoland is the worst value for money of any theme park bar none. It's hard to know where to start: the Â£132 admission fee for a family of four, the Â£15 per person for the queue jumping system (that's free at all Disney parks), or the cynical Â£2 charge to leave the car park!
Universal's one day price of $102 is still cheaper than the Magic Kingdom. The park hopper option adds $50 to the Magic Kingdom's $105 admission cost or $58 to the $97 AK, DHS, or EPCOT passes for a total of $155, which is more expensive than the Universal 1 day park to park pass of $147. Disney's 2 day hopper pass is $242, which is more expensive than the 2 day Universal Park to Park at $194.99 online price.
