How would you do this?

I'm finally getting rid of my vile, dirty cream carpet next week.
The guys coming out to lay it need us to tear up the carpet beforehand.

So, I live in a townhouse. 4 flights of stairs (it's difficult to explain but they're flights of around 6 steps with a landing in between each one) and 3 bedrooms.

I have absolutely no clue how I am going to manage ripping up the carpet, whilst sorting the furniture out around the fitters.

The stairs and landings are no bother really but I have no clue how to organise the bedrooms.
Do I just move the furniture from room to room, or do I dismantle everything?

I'm really hoping I don't have to do the latter due to youngest DC being at home with me all day (DP at work)

So what would you do?

How many rooms are they doing? Can you move furniture to another room on the same floor or will it need to go up or down stairs? Can you do it in the evening with dp's help?
