At the same time escalators are more obvious right in the center of the room and this can ‘beckon’ people to use them and enable them to glimpse the upstairs. And then on their way up or on their way down they will be toured through all of the items on display which is great marketing (this is also a great place to keep other items).
One drawback of an elevator however is that you need one for each floor. This then means that if you have a multi-story building you will need to consult with your escalators consultant in order to find out the best way to make use of the space with your escalators. It will be less cost and space effective however exponentially with each extra floor.
Some wheel chair users might also not be as keen on escalators as they are on elevators. This is particularly true of those using stairs.
