All in one suits rock

As a widower for nearly 2 years now, I need to be more courageous and have a ski holiday on my own (probably in Feb). I am going twice in March - Andorra El Tarter with mates, and mid March to Tignes Le Lac with my daughters and son in law. Last year I had 3 separate weeks skiing in Jan, Feb, and March. But this year I won't be going till March. Any recommendations for someone going alone in Jan or Feb?

I came to skiing late and never got past red runs.Since having a new hip 2 years ago, I discovered last Winter that reduced mobility in that hip made me unable to snow plough on that side. I thought that I may be able to resolve it by exercise but have been advised that this could dislocate my hip. I used to run mountain marathons so skiing uphill seems a good way to stay out in the snow and I understand that this is becoming more popular. Is Tignes a suitable resort for beginners, with the possibility of getting a lift down or easy slopes Sorry it’s a bit long winded

I'm thinking about using these in my new touring boots (Dynafit Radical Pro). Anyone had any experience of these liners or ZipFits in general?
