Cute ideas for scavenger hunt for girlfriend?

Hi you guys!!! My girlfriend and I are moving in together soon and I want to prepare a cute scavenger hunt for her on Christmas which is a week after her birthday and I'm thinking of proposing to her on Christmas Day [and I'm off that day so it makes everything easier]. I already have the ring - she told me of a ring that she absolutely loved, and I looked it up and got it for her! But now I'm just thinking where to set up the hunt [locations], gifts etc.

Any help and ideas would be awesome :D

Thank you!
