How easy etc?
A very easy walk Pyrex. There's usually a wide machine groomed piste across the glacier that's safe. Dozens of people (non-climbers/day trippers) do it every day in the summer.
From what you say I assume it's doable without ice axe and crampons.
Just a pair of shoes with some grip to stop you sliding around. It's not steep.
Shed have a better chance of survival in India.
Top tip, don't tell her. :-)
As everybody else says, the walk to the hut is a doddle with no, as far as I am aware, objective dangers beyond dodging Japanese tourists at the train station. When I was there, sadly 10 years ago, my friends who were walkers and in their sixties spent an afternoon in the hut with me. The views were stunning and its quite a picturesque hut to have an afternoon meal in.
Just banged some images on of my trip, in case they inspire your good lady.
