If the VIP add on is anything like it was for Outpost Discovery, it will be worth it.

OD it gave access to a VIP lounge with games, free food and drinks, and even surprise visits. I was lucky enough to be hanging around when they did a secret Jenn Taylor and Steve Downes meet and greet/photo op, that alone was worth it for me.

Edit:

you can also purchase the VIP package which includes early entry to the concert and convention, exclusive swag bag, exclusive meet and greet opportunities and more.
