Why is consumer research in tourism difficult?

A) Consumers experience a set of services away from their homes, and frequently on a short-term basis.
B) Only private entities are entrusted with making informed decisions about spending tax monies.
C) Information collected is often inaccurate because research takes place before tourists visit an area.
D) Service relationships are often long-term and hometown-based, which make the breadth of issues mind-boggling.
