That's nonsense.
Trustworthy programs like KMR and POTM where I was this year advertise luxury and have strong kashrus standards.
I never said they don't have strong Kashrus standards.
However, even with strong Kashrus standards, FWIU there are always compromises that not everyone would gladly accept if they were fully aware (talk to mashgichim). Especially when it comes to Pesach, while some things might just be "chumros", for someone who follows the Rebbe's directives, there seems to be very strict guidance regarding gebrokts. It is close to impossible to maintain that standard in a hotel where not everyone is aware and cares about it.
