Transportation after MVMCP

In the process of planning our Dec trip. We plan to go to MVMCP one evening. Considering a late lunch prior at Whispering Canyon. Will the boat back to WL still be running midway through/after the party? We will be driving and parking at WL for lunch and unlikely to be staying to close the park with 4 little ones.
Thanks!

It should be and if not (due to weather or other) there will be a bus option. Disney will not strand you.

Yes, folks from WL attend MVMCP so DIS has provisions to get them to/from the party just like any other night. Some transportation will definitely be running, boat weather provided will be first option of course.

In 2014 I stayed at WL and went to MVMCP . i took the boat back to WL and there was not a wait.
