Seems sudden? Between our two rooms, we used laundry at least three times, the most recent just on Monday morning with no issue. There was also no signage the rooms would be closing.
There was a day the week before when they were having issues with the credit card processors on the machines and you had to buy "laundry cards" at the front desk to do laundry. We were able to use credit on Monday though.
Although, thinking further, there was at least one washer and one dryer that wasn't working correctly on Monday. Someone else using a washer had to switch and we had to move dryers after one of them didn't really didn't dry our stuff much.
