PKI Goldpass Day on May 3

I have a PKI Gold Pass and I see that there is a Gold Pass member day on May 3rd. I was wondering if they have done this in the past & If so does anyone know what kind of crowds to expect? I live 4 hours away and want to know if it would be worth the drive or if it will be crowded?

They kindof had something like this the first year SOB was open where SOB, Drop Zone, and Face/Off were all open about 5 hours like May 3rd. I wouldn't expect large crowds and it would be probally worth it to come down. When they did something like this a few years ago I got 7 rides on SOB with one train, Several on Drop Zone and Face/off too. I also got there late. I would expect small crowds also because the twilight rides for SOB are like walk on and by May 3rd I don't think that many more will be there. I imagine there will be a lot of walk on riding and I plan to go.
