Sure ! But take light crampons anyway (alu), because you won't use them most of the rest of the way.

It depends which ones ! Any names ? As for me I prefer to never book the huts; huts are not hotels and one should be able to accomodate whenever he needs. Planning dates too early is "dangerous" because we can't predict the weather, and forcing itself to reach a place against good sense is often the cause of accidents

I'm according with Visentin.
I add: the refuges are overcrowded on summer in Pyrenees, it's very advisable to make reservation specially if you spend the night in a week-end (many people make reservation one or two months previously for friday and saturday). It's easier to make a reservation the rest of the days of the week in the previous 2 weeks, but not always. La Renclusa is under Aneto and I think it's almost impossible the reservation now (you can try calling: Refugio Renclusa). You can sleep in the village of Benasque using the bus (paying) in La Besurta (30 minutes from La Renclusa Hut). In Benasque you have some campings and lodges.
