That sounds like a better option if your bringing your 3 year old along…
A buddy of mine went on a carnival and said it was constant partying, but he said there was places for it, it wasn’t like running around rampantly partying and drunk but just the bar/casino/rooms.
I don’t think you’ll take your kid into the bar after hours anyways so its not like you would be having a bad time.
As justin said it is everyone’s vacation so of course they wanna get laid back, get drunk, etc. but my parents went on one and they don’t party/drink and they had a blast they said. Lots of good fun they said.
