I am going to Disney World with DD-2, DD-3, and DH. This will be the first time we get autographs. Does anyone have suggestions on what type of pen to provide? I have seen on past threads to be sure it is a thick pen, but would you suggest a permanent, such as a fine point sharpie, or a ball point, or any other suggestions. I just want to be sure to provide the best so that we have a lasting "impression". Thanks for your help.
