Why not do both.

We've never done Ohana but CP is a tradition for us.
Ohana best friend breakfast is our last full day tradition
We love the breakfast at Ohana.
The family platter is nice because I just find Ohana quite relaxing and like to just sit and chill and be served !!
The character interaction is great, Stitch is super funny.
We did CP for the first time last year.
Our ADR was for 8.15 and we got footage of the kids running up main street almost all alone,it is brilliant.
The breakfast at CP is buffet style and we really enjoyed it , especially the pastries !!
Also loved the character interaction but the best part was my DS's reaction to the little kids at other table seeing Pooh for the first time....he is such a softy !!
Im not the best at reviews but I can tell yu we are doing both again this year so I guess thats a big big thumbs up.
