It happens in Mid-November, which is great timing. The weather is perfect (well, it was last year- neither too warm nor too cold) and it is before the holiday rush hits (meaning hardly any long lines!). Not to mention that RATP is the first weekend that Disneyland is transformed for Christmas. That means the Huanted Mansion become Nightmare Before Christmas, Sleeping Beauty's Castle is covered in "snow," and there are a million other adorable details as well.
Last year it was just Tob and me (and some friends we met up with), but this year my parents and siblings will be joining us. Not that they are into the rockabilly aspect, but they have been looking forward to going to Disneyland as a family for the first time in nearly 10 years (I was 16, and my little brother was only 6! I can hardly wait! Hopefully Rob and I will have a chance to steal away for some beach time as well.
