Just going to put this out there:
I am now married with kids but back in the days when i was single i used to work as a mashgiach in hotels. I worked in one program which was not very fancy for a few years and that program was superb with no issues. Later i worked in a program which was definitely on the fancier side. This program didn't care at all about kashrus, all they cared about was how happy were the guests. Non-Jewish workers would bring pizza and donuts into the kitchen (yes you read right) and no one cared at all. When i mentioned it to the head mashgiach he was too scared of the caterer and the kitchen staff and it all continued. Kashrus was not at all a priority.
I emailed the owners of the program at the time, but i'm sure nothing was done about it and the program probably still runs the same way. So if you are in a hotel program be aware there is a good chance you had a good time while eating pure chometz.
So does this corroborate my "assumptions" that were attacked by Dan?
And as for Dan's claims for circular logic used, after rereading what I wrote I can see why he thought so, though its more of an issue of חסורי מחסרא והכי קתני - missing the point that the bochur that sought the fancier Pesach sedorim (to clarify for the "outsiders" on this forum, older Yeshiva bochurim in Lubavitch often go to help run, or actually run themselves, public sedorim in all corners of the world) was known by his father not to be the type that would inquire about kashrus standards.
I am not saying that he's any less holy than anyone else, just that the
emphasis and the priority list has luxury high up, while
questioning or inquiring about kashrus standards seems secondary to that.
