Congratulations on booking the Kruise!
Strange as it doesn't happen over Halloween this year, I'm sure there is a reason for that.
Unfortunately I'll have to side with the Good Dr on the appearance of Vinnie, it's never gonna happen. Things are too easy with Eric and Tommy and it's working, so there is no need to dig up the past, especially their past with Vinnie.
If they intend to re-do Creatures they pretty much have to get new costumes made, as Paul and Gene aren't the same as they were 30 years ago, and Eric and Tommy weren't there in the first place.
Either way, you are gonna have a blast, and I wish I could be there. Maybe one day again, when the kids are older.....
