Realistic things id like to see:
Entrance spruced up - I doubt we will see a massive amount of money here but maybe enough to make improve the presentation (remove them metal barriers!), electronic ticket machines too, they like to close a lot of booths during the day and you can be queueing up to 30/40 mins to even get a ticket. Along with the return of the original Entrance / Bridge theme - If they are going more family they should bring back themed music imo, theme parks should be about escaping the real world, no problem with it on special events etc though.
Audio - A lot has been fixed this year but still a few bits to sort, would be great if they could get park wide audio back to working as it should.
Park signage - I know its a small park but people do get lost, would be nice to see some signage across the park pointing towards areas / rides (Also replace that Stealth entrance sign!)
