as a comment I saw your prices at the momment and they are really low , raise them maybe double them in some occasions
also I saw you have 20 VIPs which are too many for now , don't drop the price , and don't build any more for now...
why he shouldn't drop his prices, i would be pretty sure he would earn more money if he sell of them for 500$ then just selling 40% for 800. And i believe he don't have to drop them so hard that he has to ask for 500 - i would test the waters with 600$ for the VIP seats.
