At the moment when we wish to quit the experience we still have to quit to main menu (can't there just be a quit game button straight from the park?), wait 3 seconds for the menu buttons to become clickable (there's some sort of delay where we have to wait for a slight animation of the menu screen to finish before we can click things), then click back to main menu, THEN quick quit game. It would be much more of a streamlined interface design and user experience and make the game feel more finished if the quit button was accessible more easily.
