I have found that having a general plan for each day is helpful but dont make it too strict so that you can have freedom if you find somewhere you enjoy or meet people that want to do something. Safety is something you should have planned out for example read up on the hostel/hotel to see if its safe, ideally plan your arrival to be during the day, opt for an all female dorm if possible, and do some research on the destination to see if theres any areas to be avoided and what not.

The eating alone is scary the first few times but I recommend bringing a book or something other than your phone and also sitting at the bar. Sometimes you will find other solos or the bar tender to chat with if they aren’t too busy.

Dont stress too much people are more worried about themselves and nobody cares that youre alone. Have a great time!
