As beautiful as Berlin is, sometimes you just long to leave the big, crowded city. Also sometimes to escape the hustle and bustle of everyday life and to recharge your batteries and breathe deeply. How nice that you don't necessarily have to drive far for it.
Group trips are something fine. It doesn't matter whether you're traveling with family or friends. It's nice to be able to spend time with each other again. Spend the day and evening together, have nice conversations and experience (relaxing) exciting things together.
