How much cheaper can it get?
You've paid $80 for 'non game related' stuff. Even if the tickets had been half priced (so $44 for 4 of you? I'm guessing 4, you didn't say) the total price is still $124 for 2 hours entertainment.
$44/ ticket would be pretty cheap, they DID actually have a $50 family ticket offer for that game. Which is not unreasonable. It would probably cost $30 for 4 people at Macca's these days, so really, $50 for 4 tickets is cheap as. $88 for 4 tickets isn't terrible - look at movie ticket prices.
