I get the same way about any of our Disney trips. We also leave on the 20th. Let's see...I am recovering from shingles and a bad cold that went into bronchitis, my dd from bronchitis too, my one son from a sinus infection (still on antibiotics), but my dh and youngest are still fine. I get very nervous when we go in Nov. and Jan. because it always seems someone has something. SO LET'S JUST THINK POSITIVE. Wash those hands, use a lot of hand sanitizer too. Congrats on completing your treatment too. Have fun.
