of course there are foot passenger tickets -lots of people use the lifts to sight see. With the Peak to Peak she can walk off a gondola at the top of which ever mountain your skiing and do lunch. Or easier yet you ski to the base and lunch at your accommodation or a variety of restaurants.
just off the slopes.
If food/eating together is a major consideration- I've changed my vote back to Whistler. Sunshine also requires a foot passenger ticket as the only sensible place to eat is either at the top or the base of Goats Eye you would not want to waste your day skiing down to the valley there. Lake Louise has a nice base lodge but l think anyone waiting there all day for lunch would get pretty bored as there is nothing else there.
