All cheap travel advice - I don't care where you read it - has one underlying principle. Be prepared to think outside the box.
Let's look first of all at what's inside the box.
- Limited time. You have two weeks' annual leave, you can't change the dates much, or you have to travel during school holidays.
- Limited accommodation. For various reasons (I can't actually think of any right now), you can only stay in hotels or similar.
- Limited destinations. You want to travel to a particular place for a particular reason.
