Two families going together ... can we sit together at a restaurant if one family is on DDP and the other isn't? Are there any perks to having the DDP that you can't if you aren't on DDP? ... other than convenience. We have only ever used DDP... but this year my twins will be 10, making them adults for the DDP. I am sure we can eat for less than $168/day ... so if we can't get in on free dining, I don't know that the DDP is the way to go. Will we be missing out on anything?
