OHBelle --
You're absolutely right! Three days are better than zero days, especially after not visiting Disneyland for over 30 years! Depending on the people in question and what their specific interests are, many folks can get a lot done in 3 days -- or even all that they want to do. I think you'll have a great trip. Honestly, the holidays at Disneyland Resort are so beautiful and lively that I would even go for just one day to soak in as much holiday cheer as I could. You can get a lot of bang for your buck in a short period of time during the holiday season.
I loved
Moonlight & Mistletoe too (with Tom Arnold and Candace Cameron Bure)! I do exactly what you do -- as soon as the Countdown to Christmas begins, I turn to the Hallmark Channel and it generally stays there as background sound while I am doing other things on the computer, throughout most of 2 months. Sometimes I have time to watch the movies so I do that too, of course, but I find that leaving the marathon on in the background is sort of the equivalent of leaving Christmas songs on in the background, but better -- it sets the mood and sort of creates a bubble of holiday cheer.
Plus, these Countdowns to Christmas are ways for me to catch up on the older Hallmark movies that have somehow escaped me. I think I have seen 75% of them, but there are some that I have just not made time or had time to watch. Every year I manage to watch at least a few that I have never seen before. I like the mix of the older and new movies.
Yes, pumpkin and peppermint do not go well together at all!

In my separate Halloween Time at DLR Superthread I have been tracking all of the Fall/Harvest/Halloween goodies that have been popping up in stores since July, and the number of items with seasonal makeovers was really surprising to me. I could be wrong, but it seems as though the number of items with Fall versions has increased in the last couple of years, so I can only imagine how many cranberry/gingerbread/peppermint/pine items are headed our way this year too!
Then again, even though Halloween things began hitting the shelves in July (slowly), I didn't see my first Halloween TV commercial until a couple of days ago. It was still pretty early compared when Halloween commercials used to begin (in prehistoric days), but not as early as I expected given the appearance of pumpkin-y things on store shelves!
Since your birthday is the day before Halloween, does that mean you do a combo birthday-Halloween celebration every year, or do you celebrate the two days separately? I know that some people find that a birthday close to a holiday of any kind is a blessing, while others say it's a curse!
