The main trouble was in the room. The refrigerator was making a loud squealing noise. We had to unplug it to stop the noise. That meant that we had to use extra ice in our cooler to keep the cold food we brought to put in the fridge from spoiling.
Also, when we took our elementary aged kids to the pool to swim, a series of swimming lessons for one year olds was using the pool for almost an hour, which really diminished our kids' enjoyment of the pool. This was especially true when the one year olds screamed for several minutes at a time.
When we stopped by the front desk to mention these issues, noone was there, and noone ever showed up, even though I waited several minutes.
