Educate your customers! We make it clear online sales are purely for their own personal convenience, however, others will feel differently. For us, we have three haunts on a large property you can do in any order, so go to the shortest one! Having six lines would be a nightmare! We also make it clear that the online service charge does not go to us, we do not get money from that charge, all the online sales do is guarantee you entry, nothing more, nothing less, pick a haunt and have some fun!
