Because of the high water table here in FL, underground construction is extremely expensive. an elevated train seems to be the best option to the new land near the convention center. From the WnW plot to the existing resort, I think aerial trams would work, be exceptionally cool, and be another visual advert while driving down I-4. You could literally have a Universal monorail and an aerial tramway crossing I-4 with the giant volcano as a backdrop.
