It is hard to say. In the past you sometimes got a card in the mail, sometimes a phone call or sometimes an email. They would simply say here is the phone number and wecome to wdw etc.
In the old days they did more. Now I only use them to email a room request and arrival time. Thats it.
You buy your own tickets, book your park res, and book your own dining so they not as needed compared to years past.
They no longer have dining other than the website.
I don't think anyone has been contacted yet because no one here has reported it yet. I have cl in Sept and no word yet. WAIT N SEE.
We have been doing that a lot this past year lol.
Welcome to the CL thread, it is a fun place to be!
