This website would seem very handy:
http://www.dontforgetyourtoothbrush.com/
Creates a holiday checklist for you automatically, including reminders for things like vaccinations, visas and passport as well as a comprehensive (and editable) list of things you should take which is customized to the type of holiday you’re taking (e.g. a skiing holiday has a different list to a beach holiday). Free to register, only requires your name and email address. NN/WS (unless your boss objects to you planning your holiday at work I guess)
