Two ideas: throw stuff out. 10% won’t survive the move anyway. Put stuff in storage. If you haven’t gone to the storage in two years to redeem it, throw the whole lot out.
Second: Packages under 70 pounds can be shipped via US mail. You can ship your packages poste restante to the nearest post office if there’s no one to receive your mail at your new home. This can be much cheaper than hiring movers.
Three: buy a 24 foot container—they’re cheap—and fill it up yourself with your junk. If you’re lucky the container will be lost in transit and you will be freed.
There’s a saying in the South: three moves equals a fire. Heed it. You don’t need all of what you have.
My pet peeve is that hotels refuse to accept luggage deliveries on behalf of a future guest. You ship luggage on Friday. It arrives at the hotel Monday morning; you haven’t checked in yet. Your luggage will be refused even if your reservation is for the same day. This is ridiculous.
