Topic: Travel costs make up the most significant part of the budget. It is a good idea to estimate costs as early as possible. This is how Tactical Technology Collective have done this in the past:

• Create four categories for travel costs:
• USD 0 - USD 500
• USD 501 - USD 1000
• USD 1001 - USD 1500
• USD 1501 and over
• Research travel costs for participants from each targeted country. Check www.expedia.co.uk or or www.travelocity.com for cost estimates, but also pay a visit to a travel agent for advice. Group each country into one of the categories.
• Estimate how many participants from each country will be attending and add up the numbers.
• Include extra costs for visas, local transport to/from the airport, departure taxes, and overnight stays while travelling.
