Go to ANA but don't waste your money on general registration and such.

As it is, you are going there to meet old and new friends, not to enrich those corrupt parasites.  If there is a particular event you want to attend, selectively pay for those.  Don't pre-pay for food, especially momo, because it usually tends to be terrible.  Instead gather your friends and go to a nearby restaurant of your choice.

Just my opinion.
