That being said we are renting a car this trip to give us more flexibility. For example, we are doing E-night and the boats don't run that late.
Just so you know...
For E-Nights, you are correct in that the boats do not run. However, for WL, driving really isn't your best choice.
You'll have to park at the TTC. Getting there from the WL is a bit tricky. You have to go down Seven Seas to Floridian Way, then to World Drive and loop around at the Toll Plaza. Getting out is harder, because you have to exit out the parking lot, go down World Drive to the crossover, and then come back through the Toll Plaza.
That late at night, you'll have to take the Resort Monorail to the TTC. The Tram will be running, but it's only one tram. This means it could be a 15 minute wait for it to get back. (Or you could walk, and depending on your section, this could take 10 minutes
My suggestion: Take the monorail to the TTC, and then hop the WL bus there. Buses run every 12 minutes on a fixed schedule. It's a 3 minute bus ride, and it beats walking out to the car, and then going the super long way back to the resort.
(On a side note, occasionally the MK dispatcher will run a WL/FW bus from the MK itself once the boat shuts down. It's not a regular thing, it's just a courtesy done when we have the luxury of extra buses, and management approves. Can't promise that it will be available, but there's always that chance.)
