I never take august because of this. EVERYONE and their mothers take august so everything is crowded and extremely overpriced.
I prefer getting some time in september and then spread the rest of my days the rest of the year.
Best to spend vacation in April and October. You want 6 months(or less) between your vacations to not hate your job. Summer is already good, winter also has it’s charms and you don’t want to contrast to much. But it’s not the season in my favourite resort! Well it’s a bad resort, go to Asia, spend a bit more on the tickets, much less on the ground, enjoy foreign culture. Doesn’t work for Asians though.
