Yes, get a skip, or some way of getting rid of everything you no longer need. I managed to move, unpack and start putting up pictures, within 7 hours. It's just organisation.
Label every bag and box with whichever room it's going into and find somewhere to stack everything out of the way. I think I took about 2 weeks slowly doing that on and off.
The most annoying things are things you can't pack yet lol, like kettle, plates, etc. But you can make a good start in advance- and take nothing you don't positively want. Good luck x
