Budgets for Long-Term Travel

Considering taking a round the world or other long trip? If so, you will want to consult the Website www.bootsnall.com for a story detailing the actual costs incurred by 11 long term travellers, both singles asnd couples.
The budgets vary quite a lot, but most are in the $60 to $120 per day per person range. Many of the itineraries include relatively expensive countries such as Australia and New Zealand, the U.S. and Canada, or the countries of Western Europe.
I don't know about you, but I find it pretty easy to spend $50 a day or so on average just for basics like food, transportation, a little entertainment and a few necessities like the occasional haircut or piece of clothing, right here in North America. The price can easily go higher if there are big car repairs, medical bills (dental and vision) etc. So the idea of spending a little more while travelling the world is appealing.
Of course, unless you put stuff in storage you will still need to pay rent and utilities while you are on the road, and travel health insurance is a good idea, so total costs may be higher than the figures quoted. And even storage costs something, unless friends and family will oblige.
