Summertime is usually the only time of year the weather is halfway decent in my country (Denmark) so i like to stay here in the summer and travel out of season.
Ideal trip for me was 1 month in Kyoto and surrounds in May a couple years ago, visiting remote buddhist mountain temples (see my av for example of path leading to one such), hanging out in lush fragrant Japanese zen-gardens all day meditating, and eating exotic, delicious food in the evenings.
Yoga retreats in the country side is something i like to do a couple of times a year.
Love travelling anywhere in Europe (my favourite place in the word) and visiting and revisiting the gorgeous old towns and cities of Europe and seeing fine art and fantastic architecture is a lifelong favourite for weekend getaways or longer stays.
Enjoy your trip catzilla, sounds great.
