I know under the DDP, my 11-year-old is considered an "adult" and I have to pay the full price and he can order off the adult menu. But if we're paying as we go, no DDP, can he order off the kid's menu at most sit-down restaurants? Is it still only 9 and under? He's not a big eater and I hate to pay adult prices for him if I don't have to. Trying to figure out if the DDP is worth it for us to buy or not and this part would make a big difference in our out of pocket cost. We like taking a break and having a sit-down each day, but wondering if we save by paying ourselves. Thanks!
