Not 100% this will work, but I did see cars do this once before and I did not see any restricted signs. I figure this is so those staying at MK resorts could get back without having to go the long way around. If you look on Google Map, you can see the route I am suggesting.
When leaving TTC, stay to the right and take the split off towards Hess/Car Care Center. When you get to the stop sign, right at Hess, turn right then turn right at the next stop sign. This is all Car Care Drive. The next stop sign should should run into Bear Island Road, turn right here. This should take you to the start of 2 way traffic for Floridan Way where you could then get back to Seven Seas Drive and follow it around to World and then turn on Vista.
