Pretty much, especially with the concept art of people running their hands through falling streams of colored water.
Either way, this sounds like a waste of a IP to be honest. Moana is honestly made for a nice boat ride (including the Shanghai pirates tech), a splash pad trail just by itself in Future World of all locations is not big enough and just odd. Now if they had a nice big Moana ride along with this splash pad, then it's a nice complimentary thing. But that's just not the case here.
