I think it's 99 euros for the early bird special, so if you were to calculate that into USD it'd be around 129-130 dollars. You also have to remember this is just the price of admission and you still have to pay for your hotel room and ticket to Paris and back to the US.
A dream but I tend to dream too much, It would be 130 Dollars with early bird, plus a quite expensive flight depending on where your from, that could range 500 dollars to 1000 (Or more) and then the hotel that could be 100 per day you stay there (Talking about a cheap one)
Minecon tickets?
