Busch Gardens Williamsburg has this. They ask for your information (name, address, condition) and put your information into the computer. Then, they give you a print out of the rides you can use the virtual que. On the second sheet of paper, they are spaces that the ride attendants can write return times. My mom was told that if a line is longer than 20 minutes the attendants would write down a time to return. The pass is good for 30 days. When the time is up, you can just return to get another pass. All of your information will then be in the computer. The pass is very easy to use.
