Sorry for the late reply guys. Thankfully, I found someone that's going to look after her for me. Big weight lifted.
I honestly don't know how long you could leave a hamster for but I wouldn't feel comfortable doing that. I feel badly enough that I've said the person doesn't have to check in on Christmas day but to feed her extra on Christmas Eve. She always has 2 water sources. There aren't any suitable pet shops near where I live that would take in pets in emergencies unfortunately.
Thank you everyone for your help. Much appreciated. Xxx
