Went to the event with family on a Christmas Day.
Place was full of people, but no huge lines anywhere.
Outside there was carousel, ferris wheel and couple of slides.
Indoors play areas with fake snow, ice skating ring, curling, lot of small booths with food and games. For the booth (carneval)games you need to pay but everything else is included in the price.
There was also band playing, magician show and puppet show. Kids got face paintings and there was also Elsa, Olaf and Cinderella joining the party.
It was worth the ticket and kids enjoyed the Christmas feeling. We ended up spending almost 5 hrs on site.
