Characters in Their Holiday Attire?

[WDW Princess 71]

I'll be at DLR from 11/10-11/12, and although I know it won't be in full "holiday swing" for Christmas, I know some decorations, etc. will be out and I was wondering, does anyone know where I can find photo ops with characters in their holiday clothes, like I've seen Pluto with reindeer ears, donald with a snowflake sweater, etc? I would love to get pics with characters dressed like that! Any suggestions? and also, where do you recommend is the best place to get a photo op with Mickey in general (aka shortest line to see him?) I'll be doing both DL and DCA if this helps. Thanks in advance!
