Having SunRail on this corridor, assuming they can actually offer more regular and weekend service, is definitely a change to the cost calculus for those willing to utilize transit (particularly international visitors who Disney at times offers some really good deals to attract).
The request for the CDD is definitely a positive and exactly the sort of āput your money where your mouth isā action that has been lacking from Universal and the other I-Drive businesses. I imagine some of those funds will go to ensuring there is reliable transit to and from the station which is not really well situated for walkability.
