I agree with Chax that it is advisable to book ahead in Orisson. The advantage that you have when starting out is that you know your exact 'dates' so can easily book ahead via the internet. However, it is important to note that when they ask you to reconfirm the day before for Orisson, they mean it, and if you don't do that, you might find that they have cancelled your booking.
Orisson does have stunning views if you are lucky enough to strike good weather. We were blessed in the evening to have the most superb rainbow I have ever seen, getting darker and brighter as the evening advanced, against the background of all the hills. A wondrous thing.
Just on a 'side note' here. Those walking within France sometimes found it tricky to get the bookings they wanted just after major starting points. Those who are walking are not sure of where they will be until a few days ahead, whereas those starting out had already reserved well ahead of time. People do tend to reserve in France, (whereas in Spain in the cheaper places, you can't.) However, I was very happy to discover that l'Esprit du Chemin, where I stayed in St Jean Pied de Port, has a 'quota' that they save up to allocate to those walking already from within France, for this very reason. They were also more than happy there, so long as they have room when you book, for those who have already been walking, to have a two night stay, as they recognise that those with 'tired bodies from the walk in France may well need a 'rejuvenation' time before crossing the Pyrenees. I loved my rest day in SJPP just wandering around and meeting up with people I had seen walking in previous days and weeks, all having a rest day as well!

lorax...... I have just read your reply to others so will add a bit more here. I didn't personally stay at Honto though know people who did and who really enjoyed it there. It might be quite hot in August, especially if you start near the beginning of the month.
I allowed myself two months but never took that long, so you might find yourself with time to 'do something else' at the end. But your idea of taking time to explore is something that I am sure many people allow for themselves 'second time around. It does not have to be any kind of a race.
