The trip out to WL is part of one of the internal routes(used to be the Orange route but it may have changed so ask). The golf carts are not allowed out of FW, depending on your rental period you may want to return it before HDDR, I don't think the rental is per 24 hour period but just per "day" so make sure you know when you have to return it to not be charged for another day.
That is so convenient!!
When we booked the golf cart, we were told that it is not due back until 11am the following day. They said we can drop it off at any time of the evening on the 24th if we want by parking it at the Outpost and leaving the key in a locked box.
So, I think the best plan for us would be to:
-Get the golf cart at 1pm (when we get to FW from Epcot)
-Ride around on it and explore the grounds until around 3:30, hopefully park it outside Pioneer Hall
-Go to HDDR at 4pm until.......5:45ish??
-Get the bus to WL & catch the caroling from 6:30-7:30
-Hop on the bus back to FW and pick up the golf cart and ride around the FW grounds to see the Christmas decorations
-Drop it off at the Outpost & drop off the key in the locked box
-Head back to our resort, WL.
This should be pretty easy to do, now that I know there is a bus from FW to WL!
Any idea on how long it takes to get from Pioneer Hall bus stop to the WL??
