You can go where you want, when you want! Who wouldn’t want that. There is no one to consult or ask permission.
If you travel alone somewhere where you don’t know the local language then being alone could well be a fast track to becoming fluent!
3. TAKING IT ALL IN
When you are alone you are far more likely to embrace your surroundings and be aware of things happening around you. Just sitting on your own and people watching becomes a lot more satisfying.
4. NOT FALLING OUT WITH A FRIEND
If you have ever been on holiday with a partner or buddy then you’ll know how stressful it can be and many good friendships have probably suffered at the hands of long term travel.
5. MEETING PEOPLE
I think this is the most important one. If you are on your own you are far more likely to be approachable than if you are in a group. This means meeting locals or fellow travellers is actually easier.
Side Note: If you do travel alone then safety might be more of an issue to ensure any travel medical cover is up to date.
