I spent 3 full days at Europa last week as well as a separate evening at Rulantica and I'd say it's probably the best all round theme park in the world!
My biggest takeaways from my Europa experience were...
Voltron on a smooth train is arguably the best coaster in the world! Fantastic all round package with relentless pacing (was thankful for the short pause at the turntable!) and great ejector.
Wodan is best ridden late in the day when its fully warmed up it's easily the best woodie I've ridden.
Bluefire is better than Icon and Silverstar is a very solid hyper coaster (but not quite as good as Shambhala!) with decent floater.
Arthur, Piraten and Volertarium are all elite dark rides that are easily "disney standard". Snorri, Castello and the curiosities dinosaur ride shouldn't be slept on either very enjoyable.
The food was some of the best I've eaten in a park. Fantastic vegetarian options everywhere with the Croatian food stand and French bakery shop being highlights. The food area in Arthur also had very good vegetarian/vegan options. Reasonable prices as well why can't UK parks have nice fresh food stands!?
Amazing ride operations and dispatches the queue lines never really stop moving.
Beautiful theming throughout the park and its hotels. There wasn't really a particular area that hit like stepping in to Rookburgh or Diagon Alley does but the park was immaculate throughout and very pretty.
Rulantica was magical on an evening. Outdoor swim up bar with jacuzzi seats and music cranking what a vibe. Outdoor rapids was so fun too!
With all that said there was a couple small negatives...
Merchandise wasn't great. I snagged a Voltron t shirt but it has no reference of Europa park or that it's even a rollercoaster on it. Very odd and whats with all the camp David stuff everywhere haha.
Virtual line was hit and miss. Would sometimes give you a time slot confirmation and then disappear off the app altogether or change your slot time. However as a free service it was a nice bonus getting some line skips.
I'd also give the Phantom coastiality VR experience a miss too. 45 minute wait in a cramped corridor and then the headset didn't really work with visuals and sound cutting out at random times.
So all in all Europa is a fantastic themepark and a must visit. Not the most accessible theme park in the world but well worth the trek and definitely a place I'll potentially return to annually. Hats off to the Mack Mafia
