It could be one of those, but there are other possibilities:

Skips: His voice actor (Mark Hamill) currently is playing Luke Skywalker, and the character of skips has been seen as less effective in more recent episodes.

Muscle Man: If they do go through with him marrying Starla, there's no way he can stay at the park anymore, as his trailer is way too small (Mitch will likely give it to fives)

Audrey: She was pretty much written off without much fanfare in "The Real Thomas"
