After researching all the cruises we have decided to book online a Holland American Cruise inside passage in August. Unfortunately we were told those living outside of America cannot book online, which is a shame as the prices are cheaper thank with an agent in Australia. Anyway an agent with Expedia has told me we can book with her so we are very excited. Question is - is this OK and has anyone else done this - I need to send my details, credit card number via email! I'm a little nervous but just checking with others out there. Can anyone help please.
