When supplementing core services CVBs should concentrate on
what would be of value to the customers. Customers purchase services
from the companies that will fulfill their needs more effectively (Vandermerwe,
1993). That means, CVBs have two options: (1) offer
supplementary services that are of value to the consumers and are not
offered by the competition; (2) to differentiate themselves in price,
quality or method of implementation of supplementary services where
similar supplementary services are offered by the competition. Hence
the hypothesis, stated in null form:
H1o: There is no difference in overall consumer evaluation of a
convention site with supplementary services and without supplementary
services.
