I'm taking my wife and parents to Europe soon and have a ~4 hour layover at DTW. I'm planning on using my AMEX platinum to get myself and two guests into the WL, but will need a pass for the fourth. I'm guessing I won't be able to use my upcoming CRC membership to slide the fourth in. Any way of getting the daypass in advance? What cost am I looking at? I know the CRC is around $40 for a daypass, so just curious what WL fees are.

Thanks in advance.
