I tend to agree. My kids have gone to Disney countless times starting at 14 months and 2 months forward now each 20 somethings. The only lounge bar we took them too was Roosters at POR. It is an interactive family entertainment place or they would not have been there either. Now we get to see what we were missing after a couple of decades.
The place is a highly themed nightclub. I'd be shocked if kids were allowed after a certain hour.
