Exhibit game at PaxPrime? worth it?

Hey guys, im sorry for writing two posts in a row.

We are finishing our Android game in a couple of months and we are starting to think about marketing and advertising strategies.

Some of our friends have recommended that we exhibit our game in Pax Prime 2014 in August under the inidie-developer category.

However this will be a huge commitment for us, because we don’t have a lot of money. Also we will have to travel to the US.

So my question is do you think this is viable idea for a small studio like us?
Does anyone know somebody that had already exhibited a game there?

Any comments are welcome, thanks!
