Hi Ryan
This one is a bit more difficult...
Not being a mum myself things like this not something I think about too much.
There is snow all over surrounding Pas so you could defo get a liffle sledge and that should provide hours of fun and the sides of the slopes or the flattest area away from speedy skiers would be over to the left hand side as you look at the slopes, where you find the beginner area.
If they wanted a short taxi ride over to the Grau Roig sector there they have mushing with the dogs. If your daughter likes animals I'm sure she would love that and you could ski over and meet them there after your visit to the Igloo hotel. Your wife and daughter could do it together. It's lovely just to see the dogs in action
There is a McDonalds in Pas de la Casa and I can't quite remember but it may have a small soft childrens play area upstairs. It's only a small one if there is but it could be entertaining for a short time.
