Hi,
I’ve never been to Disneyland.
If there are known franchises of restaraunt there?
You might get a carb count from the nutritional value from that particular food outlet online?
I somtimes have to “eyeball” like for like to a similar food outlet to get a ball park figure.
Sometimes there is a culture shock food that needs a reference to what I know… “oh this is like a pasty?” Oh, this is like my experience with a Taco?”
Sorry I may sound vaugue.
I used to tour in a band in foreign lands. & worked by the same rule of thumb when catered for.
Have a great time…
