Yes you have to pay to see the Dig. They have security standing at the entrance to it, and within to check for wristbands. If you dont have the daily on site guest band, or a tour band you wont get in (your room key will work though). Same goes for accessing the outside areas. There are staff posted outside each door and will make you go back in if you cant show the above items.
