I do this all the time from POR.
I take the bus to MK and then the ferry boat over to WL.
Depending on what night you go, MK may not be open when you are finished with dinner.
I take the DTD bus back from WL, and then take the water taxi back to POR; it runs until 11:00 pm.
Don't forget to ask for ketchup at your table and watch what happens!
