I build houses and have seen many people move themselves, the stress free ones are those that use a professional company to move. Some think the cost is too much but hiring vans and finding people to help on the day can be very hard and actually cost more in the long run.
My own experience of moving myself once, was half a dozen people promising to help on the day, they all turned up but after 3pm when I was already in the new house! luckily enough I had a couple of really good reliable friends who turned up early and got stuck in, I vowed that I would never do it again and have since used a removals company. The last move was 300 miles and was £2000 well spent.
Of course if your daughter and husband are willing to do it for you, then I'd take up their generous offer and go somewhere for the day while it happens....😄
