Amanda,
Thanks for asking your question to planDisney!
As the parent of two teenage girls, I am now past the need for highchairs, though I do miss those days. There is something special about seeing the Disney magic through the eyes of a youngster!
So yes, when
dining at most Disney Quick Service restaurants, like
Casey's Corner, they will have high chairs available for use. You will find them stacked up somewhere along a wall, near where the restaurant seating is located. When outdoor seating is involved, you will typically find them still in any inside areas of the restaurant, if that kind of space is available. Regardless, I cannot think of any quick service restaurant where I could not find one.
BONUS TIPNote that this applies to quick service restaurants, but not to food carts or select treat stands. Sometimes when you are looking into dining options you will find a few, like
Aloha Isle, where there is no formal seating area, and likely never any highchairs. But it can be pretty obvious from the website menus what kind of venues are more full restaurants, and which are just snack stops.
Please feel free to
write me back directly if you have any follow-up questions.
Have a Magical Vacation!
Doug
