They have the Key to the Magic, which is your room key and charge card (and entry to Magic Mornings offered during your onsite stay). It is not the ticket as well. Not yet at least (I hope never...I'm too prone to misplacing things...)
sounds like they are getting closer. last time we were there we had a separate card that was for charging and for monorail priority. and a seperate rm key, and then the park ticket. more pieces to keep track of, and i loose things easily too. lol.
