From the memory, the fridge at the Dream Castle is medium in size with 2 shelves and the bottom part of the fridge, but it might have only had one shelf.
I think there might have been a drinks/milk holder in the door but can't remember!!
I normally use the top shelf for all my medicines and then we store food and drink in the rest of the fridge!!
We've never had any problems storing anything in the fridge, it is bigger than a mini fridge that I can tell you.
