Is there a free Santa experience in Denver? (Outside of BPS)

We had a last minute change of plans and will be in Denver through Christmas. We have a ton of free places to visit Santa with the kids where we are from, but it seems like Denver doesn’t have very many options. We really just can’t afford $50+ to see Santa right now. Outside of Bass Pro Shop, are there any other free or reasonable options this coming week that anyone knows of? I am not finding much.
