HI! I just wanted to give you my personal experience (those are truly the only ones you should take into consideration and do it with a grain of salt
)
Some people feel they have been chosen by the Disney God's to come here and, let's say, make up stories to scare people off from what they don't think is fair. You will notice I'm sure there have already been some let's say, less than sweet comments going on. I truly don't understand people like this, but who the heck am I to say.
Well to your original question:
We were there in December and not only did we NEVER EVER have a problem with the A/C credits (OH BTW, there is no such thing as Adult and Child credits, they are just dining credits, well they were back in December, that may have changed you can call Disney), they servers were happy to let us pay for the kids meals separately when we felt like it. I didn't know if this was okay or not, so I asked and was told by EVERY single CM/Server that it was no problem, sure. This way we could use the extras for our signature dining experiences (which we never went to) We also split our meals sometimes because they were huge (can't do this at buffets) and were never given a hard time. Before I left for our trip I called because I knew NOTHING about the
DDP and was told you have 35 of TS, CS and Snack credits, use them at will. We didn't even use all our TS & CS meals because we ended up changing dining plans etc (you know how that goes when you get there, lol). The ONE and only thing they told us is that the children had to dine off the child's menu (that's why we split a lot too because I couldn't live with myself for feeding my children Mickey Nuggets all week). I also purchased child meals for myself using DDP credits, because frankly it's just WAY TOO much food. We swapped them for breakfasts instead of lunches and had CS for dinner and TS for lunches, it was really a GREAT deal!
If Disney has changed their system and you now have only so many Adult and so many children credits then you may not be able to do anything about, so please give DD a call.
Oh and have fun when you go, we are going again in August (ugh the heat) but it will just be me and dd who is 13 and as much as she would like to think it, she is clearly not an adult, but I will be paying adult prices for her
