For a first trip, I would stick with the basic DDP. I think the basic DDP is good for first timers and gives them a chance to sample and experience all that WDW has to offer. After the first trip, that's when people can play around more with either DxDP or no dining plan. IMO DxDP should not even be an option for someones first trip and the basic should be manditory. If you make yourself 1 dinner ADR a day it will give you a chance to try a variety of restaurants, plus it gives you a nice break to recharge. If there is a Signature restaurant that jumps out at you, book it and pay for it OOP, then take the extra TS credit and put it towards something like a character breakfast. A lot of the CS restaurants on property are not just burgers and fries. In fact, you can go for more than a week, eat nothing but CS and never actually eat a burger, fry, chicken finger or pizza.
