The Candlelight Processional is a very powerful and beautiful retelling of the Christmas Story (you know--the ORIGINAL Christmas Story). The music is phenomenal!!!!
The Osborne Lights are cool and you'll not likely ever see so many lights all in one place anywhere else.
It's not a decision I'd want to have to make, but I would choose the CP unless I had little kids. Even my 11 year old and my 14 year old loved it. My 16 year old was not going to be happy no matter what we did (unless it was a roller coaster!)
