Hi Sonia! Welcome back to the Disney Parks Moms Panel!
You have picked two excellent locations for dining on your vacation! I actually ate at both of those locations on my last visit and my family had wonderful experiences.
I have found that in most cases, the lower number in the range of prices applies to breakfast, while the higher cost applies to dinner. This held true when I dined at
'Ohana and
The Crystal Palace just a couple of months ago. With that in mind, you would have a cost of around $35 per adult (ages 10 and up) at 'Ohana for breakfast ($20 per child, ages 3-9) and $45-60 per adult at The Crystal Palace for dinner ($27-35 per child). Children 2-years old and younger dine for free at both spots. These prices are always subject to change and can fluctuate seasonally.
If you have more specific questions about dining closer to your trip, you can call Disney Dining directly at (407) 939-1947. I've found the Cast Members to be very helpful with my dining questions!
Have your camera ready at both of these
Character Dining experiences ... the interactions your family will have are absolutely priceless! Happy eating!
