We also had them in the 70's building. What we did since we didnt have a fridge we would fill the ice bucket at night and stick our refill mugs in it so it would stay cold overnight
Yes they are! If by chance your floor doesn't have ice when you need it go up or down a floor or 2 and usually you will find ice. In several stays at POP we only not been able to get ice on our floor a couple of times and we get ice a couple times a day usually.
Great....thanks for the info! We are planning on bringing a collapsible cooler with us just for drinks, and I want to be able to keep replenishing the ice.
