Reasons for insufficient homework in travel strategy

Lack of time, limited information sources, etc.

Not enough time: It takes enough time to prepare the guidebook. If there is not enough time, it is difficult to fully understand all kinds of information of tourist destinations and make detailed travel plans.

Limited information sources: the information sources of travel guides are limited, and they may only be obtained through some travel websites, travel guides and other channels, which may be outdated or inaccurate.
