more than enough reasons to point and titter — Charlie Day, Norman Reeds, Keegan - Michael Key, Regina Hall, Nick Kroll, Michael Peña, Kaitlin Olson and Colin Hanks all pop up at some point or other — there is a
notable lack of depth to Vacation's arc that these cameo
appearances can only attempt to fill in for.
