I've been thinking about making a guide for all the Winterfest stuff (and another one for all the Frightfest stuff) in the past and I may actually get off my butt and make one this year. However I'd release it after the holiday update ends because I don't want to just give it away.
I haven't gotten around to the Santas and globes for the two new PQ levels (Terrace Tundra and Gems Ahoy) because I'm not feeling all that encouraged to go get them, but what I was going to say is that I have all the rest of them. All the Santas, globes, gingerbread mans, you name them. Even all the achievements that were new for this year's Winterfest I got in less than an hour (not trying to brag).
My whole point is that you should spent a good chunk of time of the next month finding everything yourself. I know, there's a lot. That doesn't change the fact that they're still there, and you get a pretty sweet title if you find everything (Winter's Champion), which I have.
So there's some chance I'll make a guide, but the main point I'm making here is that you should buckle down and go into hibernation mode where you do nothing but search for all the things to find. If it makes you feel better, I strongly believe anyone can do it with enough determination.
