Could you do it with your nearest & dearest?

My wife & I are fairly experienced travellers & we've had many conversations on whether we could do the show. Just her & me, 50 days, togther (with the camera man) & budget our way to the finish. We've been travelling bearly 20 years togther & know how to be with each other & reckon we could, we would definitely bicker but we reckon we could do it.

We got onto could we do it with our brothers or best pals? Thats an absolute no for me. I love both of them to bits but one of them is a miserable grumpy bastard & the other one would hit the first cool bar & encourage me to blow 50% of the budget.

Was thinking do all have someone you could definitely do it with & someone you love but just know you'd leave them on a horse farm in outer Mongolia.
