Travel is full of unexpected problems, therefore you need to start, finish and publish your travel blog post in one setting, do not delay.
Many a Travel Blogger has good intentions,
"I will write this Blog post, then tomorrow I will go the Internet Cafe and publish."
The next they know, they decide to take a trip 10 hours away, the post is put on the back burner, the Travel Blogger feels guilty. This happens daily, nothing is ever finished, and one day, they just stop writing.
Travel Blog post are started by Photos, when you know the photos on your computer, then you can start to write. However, be careful, is the Internet cafe open, if it is midnight, you may not be able to finish the post and publish.
