Interesting thoughts on Liseberg.
Its definitely a very pretty place which is often tidy and well kept, especially within it’s City location.
I generally prefer Helix to Icon, mainly due to it’s layout and pacing, but will say there are some things I prefer on Icon, like it’s second launch.
Balder is definitely a fun ride, however it’s lack of styling drags it down a little. Lisebergbanen sure is a crowd eater, I think Loki is my favourite flat ride.
Shame to hear operations didn't seem to be that good. Last time I went they seemed pretty efficient, although maybe that has changed since things like the Helix seatbelts which is a shame if that’s the case. I cannot comment on Valkyria yet, but hope to return for it next year.
It is definitely true of it being one of the easiest parks to get to though. It’s just one bus ride from Gothenburg Landvetter and boom! You are literally outside the park entrance!
