This is a bit of a delicate question but what is acceptable (if there is such a thing) use of the air conditioning in the villas?

Do people tend to leave it on during the day so that you come back to a cool house?
Do you leave it on at night?
Do they have time switches so that you can preset it to come on say half an hour before you expect to be back to cool the house down?

I don't want to take advantage of the electricity bill but at the same time I do want to know that the house is cool.

I'd appreciate any comments/advice.

thanks
