Last night I thought about making a lunch ADR for this December at Tutto Italia, however when I looked for a party of 2 nothing was available no matter the date or time. However just for fun when I tried looking for a party of 3 on the date I would have made it for it became available at 12:00 PM, 1:00 PM and 1:30 PM. I'm just wondering why is the WDW dining system have no tables available for a certain amount of guests and other tables available for guests with more people in their party.
