I’ve been to Legendia twice, in 2021 and 2023.
It was definitely a park with charms and a stunning flagship coaster, however the park seemed rundown with a number of attractions either looking on their last legs or SBNO. We were actually evac’d from the twin looping coaster on our front trip as the chain snapped.
I mean Liseberg is nice, I like their flume ride, Balder is incredible and the rest of the ride lineup is generally staple. I stayed in the Grand Curiosa hotel during its opening with the ECC and consider it one of the nicest park hotels I’ve done so far. The Oceana water park looks promising too.
