What was the timing, if you don't mind me asking, i.e. placing the order with the shipping <x> months in advance and the actual travel time from your door to the storage facility door in <y> months? Have you had someone at the receiving end (storage company) receive and attest to integrity of package(s)?
We started making arrangements about 3 months before leaving (fall 2017).
We received the knocked-down crates quickly and packed everything ourselves and we took an easy three weeks to do that, although you can pay extra and have it all done for you. If you're determined you could probably do the packing in 3-4 days.
The crates were picked up about six weeks before our departure and were trucked to Charleston, SC where they waited to be fitted into a container (all this was explained by the shipping company, who did an excellent job).
There was, of course, a bundle of paperwork to do but as long as you're methodical and follow directions they don't present much of a problem.
Our crates were loaded onto a ship and sent to Rotterdam and, by prior arrangement and at a modest extra cost, held there while we settled into an AirBnB and booked a room at a storage facility. We told them when we were ready and three days later the truck arrived at the facility.
The two crates had been disassembled and all of our stuff (it had all been boxed inside the crates) had been loaded into the truck, but everything was there and they had good records of what was in the crates and that it had been transported. The drivers are only required to off-load your stuff at ground level but I'd thought to bring along some €50 notes to encourage them to help me get the stuff into the storage room on the second floor (big freight elevator, wide corridors, no problem aside from the bulk of the stuff. It took about 30 minutes to get everything into storage, a lock was put on the room and I went back to the AirBnB.
Once we'd found a flat, had some minor work done, the kitchen overhauled and the rooms painted, we would rent a car for a weekend and make a few trips back and forth to the storage facility to shift things over. That took three weeks as, again, we took it easy.
Our daughter moved from Denver to London late last year and used the same shipper and method. She and her husband also had a good experience with the shipping firm (
