Nightmare on Grayson or Terror Mansion?

Which one is better? I was supposed to travel with a friend on wednesday but he settled to go friday beside some other friends to nightmare on grayson. He said he still would go beside me to either one but is at hand any point to going still?

Answers:

Sorry, have never be to Terror Mansion, but Nightmare on Grayson is a longstanding San Antonio tradition and has other been excellent. If possible try to step to Grayson, or do both.
