Hiya, The tip is the standard 18-20% unless you have 6 or more in your party I believe. I used the dining plan when I went in November. I had a problem. I ordered a appitizer which isn't included in the DP so I put a $20.00 in the book they hand you with the bill. They took that as the tip and charged my room for the appitizer which was not my intention. I also left a tip on the table. So be very clear if you have any extras like alcohol or appetizers you are paying out of pocket for.
