Ohana is our favorite charcter breakfast, and I have never had a good experience at Mama Melrose's. A good way to tell is that it is relatively easy to get a res at Mama Melrose's and pretty hard at Ohana. (I used to think that the Fantasmic Dinner Package was created just to get people to eat at Mama Melrose's). If these are your only two choices pick Ohana, if you need a good Hollywood Studios place to eat with kids try Sci-Fi or 50's prime time, my three year old loved both and we have been probably 3-4 times to each.
