When i went with school i got on 3 rides in 5 hours.
Terrible, when i go on my own though i normally manage about 10 rides in 8 hours. But i tend to ride nemesis for like 4 times in a row at the end of the day as its queues get really short. It goes down to like 15mins as its the most reliable coaster in the park with the best capacity. The new SRQ on Oblivion is heaven aswell, i can now skip a 30 minute queue, and because the ride ops often dont notice, you can sneak a friend on with you. [:D] As often on Oblivion there ends up being 2 seats left at the ends or so, as people tend to ride in huge groups, as its so "Intimidating"
I also recommend flamingoland as my surprise nomination too. I am going to blackpool in October, so i cant wait. Lightwater valley is worth a visit just for the second half of the Ultimate and the KMG afterburner called Eagles claw. [:D]
