Good report. Understandable perspective. It seems like most attractions these days are so tourist-wired commercial that the commotion is a bigger deal than the actual purpose for being there. Ever since the big corporations ran off the syndicates in LV, the customer service has waned. Back in the day, you'd have never seen such behavior in the casino. The syndicate always knew how to take care of the clientele, even the nickel and dime group weren't bothered as long as they were spending money. Nowadays, it is like going to a McDonalds.

Most likely the reason your DND door hanger didn't work is the person cleaning the room doesn't understand english, so next time take a few feet of police tape with you.

Sounds to me like the road trip was still a better offer than the plane ride. Good for you.
