I heard that there may be blinking lights, kind of like a strobe light. Is this true?

There are "blinking lights" on the path through the forest. No strobe lights but laser dot lights. They can make some people feel dizzy.

Lights in the ice yes

They also have a trail that you walk and it has multiple different lights and is awesome! No strobe lights, but awesome display of lights! One of the best parts!!

They do not have strobe lights. But they have lights in the fountain and multicolour lights in slider.
