Timeline of a cruise; Booking to Packing

A lot of people get nervous about booking their first cruise, (or even there 50th), they're never sure what to do when; when they can expect flight tickets; their cruise tickets; how they get their luggage labels etc.
I thought some people might find it useful if I put together a time line of how the perfect cruise, (barring any problems), should proceed just so you know what you have to do/what you should expect and when.

Happy cruising
