I travel in all school holidays - that is winter, easter, summer, autumn and christmas holidays. Not long vacations at a time but from about 3 - 6 days.
In the summer holiday, I most often do one 6-7 day trip and one or two shorter trips.
I like to combine a few cities in each vacation.
On top of that I do a few extended weekend trips.
My pattern of course reflects that I live and travel in Europe.
