I have spent over 20,000 credits and then I traded some items for a spree for 16k worth of the gingerbread items, so probably almost 40,000. I made a gingerbread house so far, and then I have a holiday themed ride with gingerbread items, and now I'm working on a mini holiday village thing. I just need to have the other holiday furniture. I'm probably going to spend over 60,000 for this month.
