A point to also consider is the beach chair rental income.
I remember speaking with Andy of Andy and Cheryl's many years ago and he told me how reliant the smaller places were on the chair rental fees. The day I was with Andy was a time when the beach was very narrow and he could barely fit one row. If the beach in front of each place cannot sustain a sufficient number (I don't know what a sufficient number would be) of beach chairs, that would put more pressure on food only to pay their monthly rent.
The large places on Orient have row after row of chairs and the daily rental income must surely help them.
