No difference. The park run both events on the same day, but it doesn't matter whether you buy a Spooky Days or Fright Nights ticket. You still get access to park from 10am-11pm. Officially Spooky Days runs till 5-6pm, with HFN starting at 6pm. In practice all that means is the scare zones are friendlier until 5pm, and then scarier after 6pm.

Just as an update, I've just purchased my Halloween attraction tickets for Walibi Holland. The absolute cheapest way of buying tickets for all the Halloween attractions (which consists of 4 mazes, 3 experiences and 2 outdoor walkthrough) costs 116.50euros (just shy over £100). That includes a "before dark" ticket where you have to do 3 mazes and 1 walkthrough before 7pm, which is very tight to do since most open at 5pm. It is experience, but genuinely I think is worth it.

Walibi Holland (when I last went in 2019) was by far the best Halloween event outright I've done. Their standard mazes are good quality. They excel with their 'experiences' (of which they have 3), which are more intense, smaller groups / alone. Their scare zones, which they have several of, are brilliant, along with whole park atmosphere. It gets CRAZY busy though. I'm returning there this year for the event. I've had to budget to include ride and maze Fastrack - whilst it's possible to do all the Halloween stuff without extras, you will be rushed off your feet, and will almost definitely not get a chance to do any rides in the dark without it. I did Traumatica at Europa Park last year. Given it's Europa, the operations leave a lot to be desired (their Fastpass is necessary), and the quality of the mazes is very mixed. Atmosphere is very good though. You need to book in early September to have a chance of getting Fastpass / doing the alone experience. Linnanmaki have a fun event, but nothing to write home about. I haven't done any more, but some notable ones... -Walibi Belgium rebranded their event last year into Ibilaw. The best years of their Halloween event are arguably behind them, but they still do well (the Zombie Bar hasn't been around for a while) -Spanish parks tend to do great Halloween events, if you can deal with the queues / atmosphere. There's also a very well received scream park, Horrorland -Liseberg is pretty consistent

Since I don’t do mazes I rely on the resident expert at home for those. Liseberg's was good. Walibi Holland mazes were a bit meh. Toverland was ok. Best part of Walibi Belgium was the Zombie Bar on the lake but no idea if they do that anymore. General atmospheres are good though. Probably would need a fastpass equivalent though if available since you know, QUEUES.
