When deciding between a travel app or a travel agent for group trips, it is important to consider the size and dynamics of your group, your travel style and goals, and your budget, time, and resources. If you have a large, diverse group, you might benefit from a travel agent's guidance and coordination. Alternatively, if you have a small, simple group, a travel app's convenience and customization might be more suitable. Depending on whether you want a hassle-free or personalized trip, you might opt for a travel agent's expertise or a travel app's variety and freedom. Additionally, if you have limited budget or access to information, a travel app's comparison and booking features could save money and effort. On the other hand, if you have generous budget or access to assistance, splurging on a travel agent's service and value could be worthwhile. Ultimately, the best option is the one that suits your group's needs and preferences. Combining both methods is also an option - using a travel app for some aspects of your trip and a travel agent for others - so that everyone can have fun and enjoy the group trip!
