Ventana's tablet system was great. It would be nice if it could be accessed from our own phones too but it offered ability to order from the menu, request housekeeping items, etc. With the staffing shortages and a lot more people being more technology literate, it takes way less human capital to place orders with these kinds of systems.
However, I will say that technology is only good if the hotel actually pays attention to it. It's not going to be any good if the time to receive order is not given but the kitchen has a 1 hr wait.
