Doen't it drive you crazy when a simple thing like this causes you distress? You would have to believe that someone did some research before they moved forward with the new design. Honestly, I haven't even noticed the phone, but I will make note during my next stay. Interestingly, my gripe with the phone is that it seems to always be on the opposite side of the bed.....
Bad Black phones: you triggered my memory of the last century when the "black phone" was the one that you never used, even though it was on your desk, because it was not secure, and being behind the green door (yes, there is a color theme here) we could not even answer that phone most of the time. At that time we had gray phones that could be used for secure communications, and used them all the time to call those with similar phones.
But I agree phones are important and speakphones and two lines what we've come to expect from Marriott.
