Markus, When taking "once in a lifetime" shots always bracket, maybe in 1/2 stop increments, and go about 1.5 stops over/under the meter reading. Some people suggest 2 stops. In addition, make in camera duplicates. Shoot the windows twice or three times, that way, should there be any damage to the film - bad scratches, light leaks, damage from processing - you've got one or two more negs to work with.
As for shooting on an overcast dat, I'd suggest not, but just be sure there's no direct sunlight coming through the windows.
