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.
