This caused various problems as there was no ability to select direction of travel. My room wasn’t on the top floor, so when the doors opened I had no idea whether I was going to take a trip to a higher floor even though I wanted to go down to breakfast. To make matters worse the indication panel above the door didn’t reflect the subsequent direction of travel only the current direction.
So for example I was on the 4th floor and the lift, coming from the ground level, would arrive and be announced with an arrow pointing upwards. You would get in not knowing whether or not the lift was actually terminating at your floor or stopping just to continue upwards.
