Hi Garth,
I had a left BHR 22-10-08 and was able to manage the stairs albiet one foot at a time, no problems at all.
Not sure about getting both done within a week - you'll need to stock up on ice packs if you go that route. I found it bad enough having one done and definately would not have been able to cope with having them both done.
I live in Scotland and we are not allowed to drive here for six weeks. I tried after 5 but found it too uncomfortable and decided to wait, if I had persevered it would probably have been ok. At six weeks it was no problem just a bit uncomfortable for the first journey then all ok. 10 hour drive would be a big ask for the first one I would have thought.
If you live alone, I would ask a friend or neighbour to pop past to help especially the first week. Another good tip is to move items you would need to a reachable height, i.e. plates, pans etc.
If you want any more info pm me and I'll help if I can.
