Hi nicehead
Yes, it was good to enjoy cheaper prices especially on the Spanish side. We have produced resort price indexes for the area this year (more of that in the next edition of the book!)
Hope you get to Formigal this winter - it definitely was better than I was expecting. And Panticosa is a little gem for a half-day or so. It has steeper runs, and excellent beginner slopes. What was a really pleasant surprise was that the gondola operators prevented a scrum and ushered people towards the cabin as it came around so A) no queue jumping and b) filling cabins when necessary. They even loaded your skis for you! The slopes were policed too; amazing for a small, uncrowded area.
How did you find touring with respect to driving? Seems best to do clusters of resorts together, rather than try and traverse the Pyrenees I think - with many trans-roads closed in winter.
Also, be aware with Formigal that the pass from the French side can close very quickly when it snows - so although Pau is really close, it can be really far if you need to detour.
Do report back if /when you go
