The Vdara's management is well aware of the threat to guests, which it attributes to a "solar convergence phenomenon". The architects had taken this into consideration, and "hired a consultant who decided to place a thin film over the window which reduces the sun's effects by 70 per cent".
MGM Mirage spokesman Gordon Absher admitted: "But even with that, when folks are out on the pool deck, on some days people will feel this reflection and the heat associated with it."
Absher explained that there's no easy fix for the problem, since the hot spot will shift according to the season, and so throwing up a few extra-thick umbrellas would mean their continual repositioning.
He said: "This is quite literally an astronomical challenge. We are dealing with a moving target."
Although the Vdara is mulling hi-tech solutions, it's immediate response to the death ray menace is to fall back on "larger, thicker umbrellas" and "maybe some large plants".
