I'd gather that Universal will draw more of the 54" and up crowd than SeaWorld will draw back in of the 48-53" kids.I won’t be so quick write off Icebreaker yet. That’s a family coaster with a minimum 48” height requirement. That’ll draw in crowds because it fills a void in SeaWorld like Verbolten does for BGW.
And although not officially confirmed yet, my friend in management at IOA was informed Velocicoaster will be a 54” minimum to ride.
It's good that SeaWorld is going in the direction of having more shorter kid friendly thrills, but they'll need more than one coaster at that height to be attractive to families.
