Most people walk the Tour du Mont Blanc without a guide, and for good reason. It is waymarked the whole way, busy enough in season that you are rarely alone on a col, and there is a hut or a village at the end of every stage. Navigation is not the hard part.
Three things decide whether self guided works: the booking, the variants and the weather calls.
The booking is the real work
Eight nights, three countries, three booking systems, two currencies, and reservations that open in January and sell out by February. This is the part that makes people pay for a package, and it is a fair reason to.
If you are doing it yourself: decide your direction and dates first, list the eight stage ends, and book them in one sitting in January. Start with Rifugio Bonatti and Rifugio Elisabetta, because everything else has more availability than they do.
Navigation, honestly
The route is signed throughout with the TMB waymark and timings on yellow posts. Carry a paper map and a GPS track on your phone with offline tiles, and you will not get lost in reasonable visibility.
The exception is thick cloud on the high cols, particularly the Croix du Bonhomme and the Fenêtre d'Arpette, where the path over rock is easy to lose. That is the one situation where a compass bearing matters.
The variants worth taking
Fenêtre d'Arpette over Bovine, if the weather is good. It is the highest point of the circuit and the best single stage on it. In rain or lingering snow, take Bovine and do not feel short-changed.
Mont de la Saxe balcony over the low Val Ferret, almost always. The valley alternative is largely a road walk and you would be skipping the finest sustained view on the route.
Col de Tricot on day one if you want the harder honest start rather than the Bellevue cable car.
Bail-out points
You can leave the route on most days, which is what makes self guided low risk. Valley buses run from Les Contamines, Les Chapieux, Courmayeur, La Fouly, Champex and Trient. A bad forecast or a bad knee costs you a stage, not the trip.
Know these before you start, so the decision at breakfast is a choice rather than a panic.
When a guide is worth paying for
If you want the hard variants regardless of the forecast, if this is your first multi-day mountain walk, or if you simply do not want to spend a January morning booking refuges, a guided or self guided package earns its money. There is no purity test here.
