After a couple of PM's about this, I should add that if your partner want to come on the actual trip and then you both want to stay on, you're more than welcome....
We're quite happy for them to ride in the Support Truck, either for the off-road sections or just for the odd day, or even the whole trip- it's a good way of seeing the unusual /spectacular parts of Morocco on a bike trip without actually being on the bike too much
