My wife and I did the self-guided Tour de Mont Blanc trip. We thoroughly enjoyed the trip and the organisation by Salamander was very good. It suited us since we only had a limited amount of time, we didn't want to have to carry all of our luggage all of the time and we wanted to mainly stay in small hotels rather than mountain huts. Look carefully at what the corresponding guided tour includes to decide if it is for you. We didn't fancy doing the long walk down the valley from Grand Col Ferret to La Palud, so continued on the TMB path via the Refugio Bonatti Hut, making a very long day. Similarly we didn't want to do the bus ride up the valley up to Val Veny, so caught the gondola from Coumayeur and followed the TMB from there, making another very long day. If you have time, a 10 or 11 day option might be a more relaxed way of doing it, but you would need to have some stays in mountain huts. The accommodation that Salamander booked was fine and they were very helpful in the booking process. Their accompanying notes were also very useful. It was nice to meet up with the members of the guided group in the evenings without feeling constrained by set times and routes during the day.
