Got there at 10, and in 7 hours got five rides before finally giving up and going home. No fast track, and queueing for front row each time on the four coasters we did, but it was just too demoralising to be honest.
Finally got to go on Stealth though (it's great!), and the one non-coaster ride we got was Slammer - so no complaints on that score. Won't attempt FN again though.
