It's very easy to explain the cost of a science fiction convention, and an enterprising con could probably put up a jazzy table on their website to push the idea:
Worldcon = $210 for five days. Assume 12 hours entertainment for three of those days and 6 hours for the remaining two. That's 48 hours, or $4.37 per hour.
A movie at the cinema = $16.50 for two hours, or $8.25 per hour.
A videogame like Halo might take 20 hours to finish, but costs $100. That's still $5.00 per hour.
Dollar for dollar, SF cons still represent damn good value for money.
