Hi, I don't think Ramuntcho has a website we booked a night over the phone. Hotel Ramuntchos phone is the area code for france, which for me is 0033, + 0559-373-517 (I always forget if you drop the 0 off 0559 when dialing from outside the country but one non-connect will tell you!)
It is a great little spot right in the thick of things and a nice treat to have it as your starting point as you are literally a step away from the rue de Citadelle your route out of SJPP. Try and get a room with a balcony, they looks out over the old city wall to the hills, nice spot to sit having a beer and watching people as they climb up to the ramparts.These rooms share the same aspect as the dining room which is lovely but if the menu is a bit up-market for you there is a very cheap and cheerful little restaurant just opposite the side door into the hotel on the rue de France as well as lots of others in the town of course.
You only need your name the number of nights,your arrival date plus the kind of room single/double with bath. Once you have figured that out it will serve you well not only in France, and if you don't (yet) have spanish, in Spain as well at least up to Burgos as French is widely understood on that part of the route.
Are you going to stay in hotels and pensions all the way? If not and you are traveling by yourself its great that you are staying in Orisson as you will have the opportunity to meet up with other pilgrims going over the next day and start forming your own 'pilgrim network' which is such a support and joy and an integral part of the Camino.
Say hello to La Vierge de Orisson for me and, if you have a bit of thread/ribbon/string, or any other little personal offering you can tie it on the statue or leave it at her feet with your prayers -some people find this a bit weird but it was a reassuring little ritual for me, and plenty of others from the look of it. Bonne Route
