I can't give specific suggestions, but often if the refuges are closed, they will still have a 'winter room' where you can sleep year round. Closed often means they are just not serviced so you have to take your own food and a sleeping bag.
Hadn't considered they might still be open in that regard. I guess it'll be a hard sell to convince the gf to subsist on dehydrated meals for the best part of a week.
