I have enough money for the Gigabits all-nighter, but $15 is quite a bit. It's an interesting business move to charge so much, but it seems to be under the assumption that that's our only option. So the circumstances are:
NC (7-8 people), Melbourne (4-5 people), Tampa, and Crom's(4-5 people) which is about a range of 15-18+ people will be playing (I didn't really count it). Gigabits can host this for $15 per person, but TheLaw can host this for free, and both have an adequate amount of TVs.
But the question is, can TheLaw host this many people in his home? Remember, it's greater than 15-18 people. If so, then his house is probably the better alternative.
One more note: Gigabits provides food and drinks (albeit over-priced). When you're waiting your turn for a singles match at 2 am, you will get hungry. There's another question for TheLaw.
