Halal tourism. Halal tourism is a subcategory of tourism which is geared towards Muslim families who abide by rules of Islam. The hotels in such destinations do not serve alcohol and have separate swimming pools and spa facilities for men and women.
A Euromonitor International report released at World Travel Market in 2007 in London says that there is potential for a boom in halal tourism in the Middle East. The report mentions a market for a halal startup airline, which could provide halal food, prayer calls, Qur'an in seat pockets and provide separate sections for male and female travelers. Many international hotels do serve halal food that is slaughtered in accordance with the teachings of Islamic Sharia and is free of any substances forbidden by Islam such as pork and alcohol.
