Going to cons literally changed my life. Regardless of who I went for at the time.

If you've never been to one, my advice is to go. Go to at least one. Because at the very least you will see some amazing cosplay, meet some cool people and talk to some cool artists or vendors. They're never regrettable even when the actual co itself isn't well organized or well put together (and I say that assuming that Alamo Comic Con is probably wonderful because I know nothing about it specifically).
