I would get the heavy platinum pan if available. And use the Baker's flour cooking spray unless you know something else would work as well. Silicon haven't gone that route yet, hear it's good. My three are Nordic Ware and heavy, not necessarily all platinum. But any metal should work if prepped right.
I think the village is adorable. Here is the one with the pine trees (I think the photo is the kind that you can't {easily} embed.

You might find something if you google lights for cakes. Walmart has these:
"Illuminate floral arrangements, centerpieces and even place settings with these Non-Blinking Mini Party Lights. They have an exclusive rubber gasket that allows for submersion in fish tanks, ponds and pools. These white party lights can last up to eight hours. They have a built-in loop for convenient hanging and are ideal for holiday, seasonal and party occasions. Darice Non-Blinking Mini Party Lights, 12/pkg:"
A little pricey and all you need is a kid to choke on or swallow one. I'm a negative thinker when it comes to a lot of things :-(
I just ordered a silicone covers the village pan on Amazon. For some reason it won’t get here until Wednesday, that seems more like three or four days than two which is what prime is supposed to be.
Oh well, I can’t wait to try it. I have had good luck with the silicone large Bundt pan I have, after I figured out that you had to let the cake cool completely before trying to remove it. So I was thinking the silicone might be easier with the teeny tiny little village cakes since they will be must much firmer when they are cold and I could sort of wiggle the silicone mold a little bit to get them out. With the Metal pan, they would have to come out while still warm and they would be softer and more likely to not come out in one piece. At least that was my thinking. Not to mention the silicon one was much cheaper and I also get a gingerbread house kit with it :-)
