The easiest way to obtain cruise brochures is to visit a "High Street" travel agent. You don't have to book with them if you don't want to. If you are unable to do this most cruise lines have a web-site and invariably offer a brochure service and as you obviously have a pc they would send it, at your request, to his address. Lastly if this fails ring the freephone number for this site and speak directly to them....they are very obliging people.....regards Neil Dow.
You can go online and find many online cruise brochures- just type in the a cruise company -all listed down the left margin here on this site-and they all have downloadable brochures.or...go to a travel agent on any high street and ask for their cruise brochure.
You can also call agents like this one who as neil says above are more than obliging. They helped me decide on the best type of cruise lines that would suit me and my wife best, then sent out those brochures. That way I didn't have a great stack of brochures I didn't really need.

The weekend papers have hundreds of cruises listed. I personally get the Express at the weekend especially for the cruise holidays.
