Based on standard school/club renting usage requirements, say 2hrs minimum billable time per day, a month’s rental would be very expensive. To make it viable you would have to fly every day and that would be a pretty exhausting 1 month holiday.
I have heard there are places where you can do long term rental but that involves a heavy cross-subsidy from short term renters, so would work only if there is a lot of money sloshing around and everybody is happy and smiling 
But a month off work and having a long flying holiday, say a flight every few days, would work nicely because you could pick nice weather for everything. You could do a lot of Greek islands for example.
PlusOne flyers in San Diego requires a minimum of 1 hour per day of rental. I guess it is Caba’s plan. It’s a good outfit, many French go fly there. Some friends of mine will do in September.
