Well, lets fly away from birds and look at when you're going to fly away. What month are you planning to take your summer holiday?
September was the clear winner with 67% of the votes selected from the following:
I think the results of this vote are absolutely hilarious. Technically speaking, the summer months are June, July and August - none of which got any votes at all. So nobody is taking a summer vacation if you're to apply the strict sense of the word summer. The majority of votes going to September which is a beautiful month to go away - don't you just love autumn? Or fall if you have an inclination to call it that.
Other than the person not having a summer holiday (which I suspect may be Mr O), I wish you all the best and hope you have a great time.
