We are on the Dining Plan where everyone in the party gets 1 table service credit, 1 counter service credit and 1 snack credit per day. How do we handle the tip when we use the table service credit? Is it A) included in the credit, B) to be left by the party (how will we know what our total bill is if its covered by our credit) or C) can I put the tip on my room card? Please help a first timer at WDW.
