Remeber also that you are in Orlando and from what I have seen Universals halloween thing looks crazy and not to mention they have the movie experts to make the coustumes and efx. The plus to your attration however can be that it is cheaper and that perhaps you might look into putting attrations for the younger crowd. It seemed on the site that Universal's attractions ar more geared for 13 and older. So that could be a plus for you and for the locals! Good luck and hope you have fun!
