Singles vacations over 40

I am soon turning 40 years old and i am starting to be interested in singles vacations for my age range.
I am goind to do some research on the available singles vacations for over 40 years old people. I have to admit that this research is not mainly for me, since i will be probably not be interested very much in singles vacations (i am married with kids) but i look around and I see an important number of people that might be very interested in this type of travel.
