We're Canadian, and have visited Disney World at least once a year for 34 years (AP holders). However, for the first time, we're planning to go on a Disney cruise. Here's my stupid question: When I search the web pages, there are firms which have far, far lower prices for the cruise than is quoted on the official Disney pages. Should I consider them, or is there a reason for paying the full price that Disney charges. Please help, and thanks.
