We are huge Stitch fans, and one time we waited at MK at the location where Stitch was suppose to show and he never did. We had a cm call and we were told he should be there within the next 30 minutes, well 30 minutes later and no Stitch. We were bummed. Now he might have showed later, but we checked back and never saw him. So with that said, if your son is still really into Stitch at the time of your trip I would just do O'hana to be on the safe side. We have always had great interactions with Stitch there and really it's fairly a reasonable price for Disney standards.
