Someone on Reddit posted a photo after they stayed at a Marriott in Florida . There was a sign on the mini-fridge that said they'd be charged $50 if they put any of their own stuff in it. "The refreshment center is on a sensor. Use of the refreshment center for personal storage will automatically incur a $50 charge."
(Here's the photo.)
If they do charge, a few people mentioned a hack to get around it. Call the front desk and tell them you need a fridge to store your medication.
