From previous years, it has improved slightly in introducing a wristband system and a fireworks display later this year (that is, if it's not cancelled). However, since I visited this April, there still seemed to be the same old problems. Engineers would tend to work on one ride for 10 mins, then walk off to another, then another, etc, managing to only be able to fix MC by 14:00 while JO's lift hill was still knackered. The staff were reasonably friendly, even though most could fit into the bracket of chav-with-GCSE.
The main problem for me with FI now is the management behind it. The engineers are badly managed and should work on one ride until it is fixed and not just leave it looking like a construction site. The ride hosts/ops have no understanding into the technicality of the ride they are working with, leading to rides easily being classed as 'broken, awatiting technical assistance' and the words 'new theming' haven't seemingly passed through the main office for many years now.
The blindingly obvious, most infamous attraction of FI is the market, which clings onto the side of the ride area like a bubonic infection. Once they get rid of this and the vast amount of old, cracked concrete then that would immediately be a vast improvement for them. Perhaps then they would have space for the rides to breath, rather than being cramped all together as they are now, allowing for theming and more permanent rides.
The new splash zone, if it goes forward, could be a nice addition to the park (whatever they're classing as a 'splash zone'). However, from the plans sent through to the council, the entrance doesn't look all that appetising.
