Gender differences are critical in consumer behavior theory. As the purchase risks, the intangibility and perishability of travel products exceed those of other products, the overseas travel decision-making behavior differs from general consumer decision-making fundamentally. This study clarifies whether the thesis of gender differences offers an appropriate explanation of tourist hesitation and the justifiability of destination decisions. Based on multiple regression analysis of data from 443 tourists at Taiwan Taoyuan International Airport, gender differences did not significantly influence on tourist hesitation and the justifiability of destination decisions after controlling other possible influences. Comprehensive management implications for travel agents are discussed.

Tourism is one of the major service industries today, one that faces increasing consumer demand for customized products and services, of which FIT is a commercially important representative. Tourists desire overseas tourism products that they can design or arrange themselves instead of purchasing existing package tours. The literature pays scant attention to the relationships among tourist knowledge, customization, and satisfaction from the consumer perspective. This study shows that tourist knowledge positively influences customization and customization affects satisfaction. This result also appears that customization presents a mediating effect. Finally, comprehensive management implications for tourism managers are discussed.
