More beneficial to Disney, it will draw a virtual queue waiting crowd which will have them spending money while they virtually wait.It'll be interesting to see the public/media reaction to the attraction's duration. With Guardians/Hagrid being a ~2.5 minute long coaster, I'm sure there will be lots of "While Tron is fun, it pales in comparison to the other similar new additions throughout Orlando that are 2x as long."
It'll still draw crowds though since Disney does a heck of a job with marketing.
I think Tron's short length will not only be more noticed(as it has been) by other riders, but also compounded by the fact that it is block break paced. More than a couple block brakes in the dark in under a minute. Not only is Velocicoaster longer, it covers more track with more speed for the thrill. So durration and track are much longer. Guardians and Hagrids are longer, arguably more thrilling and their block brakes are show scenes and a different environment than more dark.
