bump.
we should probably have a lucky draw in the carnival, with the high-demand prizes like iPhone, admission ticket on the rides and for the game booths, etc. which should be higher than expected profit AFAIK.
after reading other idea's and comments.
just entry admittance should be under $15.. and people then separately pay for rides they want
but also have the day pass that includes a number of rides, etc for a higher price (obviously more then just entry, but less than 50% of disneyworld)
if people choose to pay via bitcoin. it still costs the same amount of fiat to buy the amount of bitcoin needed(no discount).. but its a VIP day pass, allowing for better prizes on game stands, better seating at shows. longer rides, queue jumping, etc.. maybe even a free pizza slice.
try not to make bitcoin seem like a discount currency, but an exclusive VIP status currency
afterall the ticket stands handling fiat are gonna make losses. EG employing people an extra couple hours after gates close to count up the bank notes and take them to a bank. where they find they lost a bit of fiat from ticket staff giving the wrong change etc (you know standard fiat problems)
so its better to give customers some extra's for using bitcoin as it reduces time/cost waste by not needing to handle fiat
as i said before you might want to partner up with existing events/carnivals/county fair organizers so that you can dip your toe in the water without having all the headaches of fully managing one.. then once comfortable.. then organize your own
