I’m a Dutch architect, developer and I’ m arranging 10-days tours based on architecture, nature and culture around the world. I have booked a trip to Dubai from October 20 to 29 for promoting myself and my business and also looking for other opportunities. I need a little help in finding good network places and am asking you for some suggestions.

I would suggest that your first step is the Netherlands Business Council.  They host networking events that will put you in touch with the relevant people also it maybe worth also contacting the Netherlands in Dubai group as they may have some contacts. Talk to an outbound travel agent such as Al Arabi Travel.  You could also join Business Networking International Middle East branch and lastly the Dubai Department of Tourism and Commerce Marketing.  Hope this helps and good luck.
