MMMMM....I have changed my opinion slighty and think the only thing can help at all is to pay for my airfare so I can check out the new place myself????

No???
Wellllll, it was worth a try - it sounds fantastic and South Africa is one place I'd love to see!

Seriously, short lead sessions are best and walking only on fenced in property for a couple of weeks is ideal - you lucky thing!

I'd be tempted to say carry on as you are and for the first week at the new place do not do any lead work. Give youself a chance to sort out the house and get settled. Then when you are "in and sorted" begin lead work again with the new ideas. Continue to treat Digby as dominant for that time though.

One thing to watch is carry on the lead work for a few minutes before releasing the dogs to run free when you reach your destination. I am assuming that both of you take one dog each. A useful excersise is to get both dog's to sit and then you or your husband takes the dog they have for a very short session of sit, down and heel and then you swap dogs and you do the same. Then your husband takes the dog he has not worked and then you do (hope that makes sense) before you let them free.

If you can get a little lead work before every free run - perfect.
After a couple of weeks increase the leadwork and vary the places the lead work happens, gradually more distractions. Vary the speed of your walk and the timing and number of commands - this is the hard time to keep your enthusiasm going. Pretty soon the dogs' will be so busy paying attention to the next move they will have no time for worry or passer by's.

Good luck with the move!

Have a look at the question on stairs....the ssssteady is a brilliant attention keeper if used well.
