April was an intense month for the Dopplr team with our Milan release launching both boutique hotel bookings and the ability to calculate the carbon impact of your travels. Many thanks for the all the feedback and improvement ideas we’ve received.

Now we’d like to look forward with the Dopplr Mid-2008 Travel Outlook. Where next? The image above shows where the growing Dopplr community (in the aggregate) will be travelling from May to September this year.

The top 20 city destinations are New York, London, San Francisco, Paris, Las Vegas, Chicago, Berlin, Washington, Los Angeles, Boston, Barcelona, Portland, Seattle, Amsterdam, Rome, Tokyo, Copenhagen, Dublin, Toronto and Stockholm. (To see the city pages you’ll need to sign in to Dopplr.)

Compared to the other months of the year, big movers and new entries in the top 100 destination for Mid-2008 were: Venice (jumping up 47 places), Lisbon (41 places), Budapest (39 places) and Montreal (26 places). Nice, Cannes, Florence, Athens and Black Rock City (home of Burning Man) all enter the top 100 for Mid-2008.

London continues to be the most populated “home city” on Dopplr with other cities closing in. The top destinations Londoners will be visiting in Mid-2008 are: Paris, New York, San Francisco, Dublin, Amsterdam, Berlin, Barcelona, Helsinki, Los Angeles, Stockholm, Lisbon, Singapore, Brussels, Munich, and Rome.

The summer months of the northern hemisphere are clearly a time for international travel. The percentage of international trips is 54% in May-September (compared to 46% during the rest of the year).

Finally a prediction: the Dopplr end-of-year travel outlook will see New Delhi, Bangalore, Shanghai and Beijing rising up in the top destinations!
