I travel alot, but I am not wealthy. The only way I can afford to travel so much is by saving money wherever possible. This includes expensive taxi's and airport transfers. I am very interested to hear of places where I can visit and walk to the centre of the action. I'll start with a couple...
A brisk 20 minute walk from the Montego Bay Airport will have you on Gloucester Avenue aka "the Hip Strip".
A 10 minute walk from the terminal at the Denpasar Airport in Bali you'll be well along the busy and hotel filled road to Kuta Beach.
You can walk from the Billy Bishop Airport in Toronto to the central business district in less than 20 minutes.
Does anyone have other suggestions?
