Removing the elevator attendant is kinda like removing the park ambassadors. Seen on the bottom line, but lots of intangibles that cannot be measured are now gone.
Anyone that has worked the elevator attendant position can attest to the guest interaction that you got (and more so than probably any other associate position in the park) and undoubtedly had positive impacts on a guest's experience that day in the park. Whether it be answering a question, offering up ride or food suggestions, to just maybe listening to them vent a little bit if they had a bad day, it is all valuable interaction that is now gone.
