Totally agree. I was just copy and pasting the policy as I read it on the website, didn't say they enforced it. On a different thread I said that they don't enforce the "not permitted" dress code for dining rooms. Some were very quick to come and tell their first hand stories of being turned back.
Just one response "I can confirm having been turned away from the Steakhouse on Mardi Gras last year. My then 15yo son was wearing nice shorts and a button-down shirt. We were told he could not enter wearing shorts. We ran to the room quickly and changed. No big deal, but it did happen."
That's why I also said "I would suggest your wife wear what she wants but be prepared to be turned away if she is wearing something not permitted. Can either change or eat at the buffet." It seems, like most "rules", it depends on the person left to enforce them. Could get different results depending on the staff or even the day, who knows. It just seems random.
