Hi there, this movie was maybe 1970s or 1980s.  A group of older women having a reunion of their dance troupe are staying on the top floor of the hotel, and for some reason they can’t get down the stairs or the lift and no one knows they are stuck up there and they can’t get anyone’s attention.  I think they start dying one by one.  One woman squeezes herself into the dumbwaiter to go down that way but of course the cable breaks and she falls to her death.  That’s about all I remember – does anyone have any idea what this movie was called?

Thanks
