The size of the team has an impact on individual team member's stress level. The cultural differences are more pronounced with a small team, and therefore, the difficulty of the trip is somewhat dependent on team size.
The level of difficulty will also be dependent on the number of major cultural differences that are present in the trip: country, language, ethnic group, housing (residing with the team or with host-receptors).
