WElcome to the DIS!!
I'll give my input,
The picture package is new - and right now if you were to book one big party you would get just one package. If you were to book 2 separate bookings (one for you, one for your son granddaughter lets say) you would get 2 picture packages (and still pay the same price) BUT you couldnt get everyone in the one picture if you book it the second way - from what I've read...
However, keep in mind this is all new - and Disney and the CM's do like to make magic happen, so it wouldnt hurt to look pitiful and ask about getting 2 picture packages one for each family ( 6 adults, or 4 adults?) Anyway you just never know!!
Read the reviews here on Cindy's breakfast, or try and use the search button, key in Cinderella Breakfast, or CRT Breakfast - you will get lots of opinions - so keep in mind we all have different opinions!! (esp me!! lol)
From my experience Cindy's is so much more than the food - the price is way over the top for breakfast (in my opinion) you are paying for the characters time, you are paying for a picture package, you are paying to eat in the castle - oh and they do have food there!! AND so many waiting to eat and experience the castle which means - it can seem "rushed" IF you want it too!! (trust me, there is lots of fast movement by CM's and Princesses)
But its the CASTLE!! (you think Disney knows this???!!!) So I booked it for our trip!!
For PSB - that's now on our must do, as dd loves Princess Aurora and she doesnt always come to the Cindy breakfast (and I dont want to wait an hour in toontown this year!!) We did it our first year and LOVED it!! The ambviance is not the castle, but the CM's that wait on you are from Norway, and its great to get them to open up about their country, and hometown!! The characters for where we sat seemed to go much slowler, getting down on our level, talking, laughing, and hugging dd more!! (but that's just one persons opinion!!)
I enjoy breakfast - I love scrambled eggs and bacon - its all good for me!!
