Tourist Visa to Hong Kong

I am planning a visit to Hong Kong with my Family (My-self, wife and 2 young children) for 5 days. We are planning to visit Disneyland and few other tourist attractions. This is the first time we are visiting Hong Kong, but we have visited other countries before.

In the visa application is it must to have a sponsor signed on it. I do not have any friends or relatives living in Hong Kong, who would sign as a sponsor.

Does this mean that I cannot obtain a visa to visit Hong Kong ?
