But does it only make sense for the summer? And can you be profitable for just shabbos? And essentially it's just a program taking over the hotel for summer
The break even for a regular standard hotel is 40% occupancy.
A high-end hotel or any hotel with a lot more f&b has a lower break even % since f&b is where the money's at.
An extended stay hotel will have a higher break even since they tend to do less f&b.
To be fairly profitable you need 75% occupancy.
I'd say kosher has its own unique set of challenges, so even if you do a lot of f&b, it cost more and is therefore closer to a standard hotel.
