You might reconsider where you have employees place the towels on the beds. If the towels and pillows are allowed to be place back on the same place on the beds when the acrylics are hot you can end up with "crazing" of the acrylic sheet under this area (the rest of the acrylic is allowed to cool down, but the pillow or towel holds the heat under this area for a longer period of time... the difference in the two temperatures cause the acrylic sheet to go cloudy, and the structure of the acrylic begins to craze with spider veins.) Once you have had this happen to you, you'll have your employees move the pillows and towels to different positions on a reqular basis.... some months up to the head, some months to the bottom, etc.
