DH bought one today. I didn't see the packaging, but on the actual ticket I have the front says
Universal Orlando Multi-Day Ticket
Universal Orlando and Universal Islands of Adventure
Guest First and Last Name (please Print)
Guest Signature Required
(Guest counter signature is required for each visit.
It also states Photo ID required
Back:
Has Costco on it, states "this ticket is valid for both Universal and Islands for the length of this ticket" Valid any three days until 12/31/2013.
3 day +PTP . Access to both parks per day-CW included
There is a barcode.
We will be using this Sunday. It is a great deal since we are only doing 1, maybe 2 days and will be back before 2013. If you are planning on going before then I would start to buy these. I was going to buy the Mapleleaf tickets, but they would expire now, and we only plan only the 1 or 2 days so this gives us a future day also.
There is no designation of adult or child on Tix.
Hope this answers a lot of questions.
