Expressed Breastmilk

Jasmine

I’m in a hotel for 2 days and their fridge doesn’t get cold enough despite me setting the temperature as low as possible. Is it okay if I keep his expressed breast milk in ice water in my cooler? (I’ve been replacing the ice as it melts) Have any of you done this? I cannot have this milk spoil because it’s so hard for me to pump enough for daycare 😩 T.I.A.
