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.
