I think one night is more than enough. Like you I don't worry about the rides, but make it a point to take in the parade, shows and fireworks. And of course the trick or treating. I don't know of many who have done more than one party in a year.
Thank you I forgot about the fireworks :hammer: that is a must do!! Do they have shows? I know they have shows at the MVMCP but I wasn't sure about the Halloween party.
