I am leaving for budapest in June for 10 days with a friend that is working for 4 days of the trip. I am considering taking an overnight train to Prague and maybe another spot. I have 3 alone days to see outside Budapest and have seen several areas of Hungary but it has been over 10 years. Trying to decide if I should do day trips in and out of Budapest and stay in Hungary or see a new country. Any great suggestions for a female traveling alone?
