It's Florida you are barely above see level and the ground more than 2 feet down is all sand there would be no possible way to build a tunnel especially under the foundations of other buildings
They could build some kind of sky bridge...that would work thematically. They are going to have such a huge demand for merch, keeping that little souvenir dump shop with the lightsaber, whatever stuff would give them room to sell additional stuff in SWGE.
I really hope they keep it for capacity. I'm not holding my breath.
