How much leisure time do I have?
Depending on the program and the program schedule.
For the Mexico program, because of the rural and urban program, most students have Saturday, Sunday evenings off and some weekday evenings. Some weekends are reserved for scheduled field trips that are educational in nature.
For the South Africa program, the weekend is usually reserved for field trips, and some weekends and evenings are left open.
However, it really depends on the purpose of your travel. If you are traveling in order to have a "vacation," then it is advisable that you DO NOT APPLY to the program, as the purpose and focus of this program is personal and professional growth, and what you want to do and get out of the experience there.
