You can never tell about the weather, we've had many christmas' where its so hot everyone is wearing shorts, and others where you're bundled up.
They have a christmas parade that starts right around Thanksgiving. I just love to watch the parade, and we try to go an see it at least 4 or 5 times each christmas season. One of these years I'm going to have the time to take the christmas tour.
Don't know if they'll have the holiday fireworks with snow this year or not, since it's a new fireworks show. We'll see.
As for the ages of the kids. It's never too young to go, your kids will remember for a few years, even if they won't remember when they're 30. We buy our kids toys, take them to the park, have birthday parties, send them to preschool, etc. and they won't remember any (or much) of that when they're older, but it's still a learning experience and gives the children a wonderful fun time, and the adults in their lives wonderful memories of watching these children.
My daughter has been going to
Disneyland since just before she turned 2 months old. I remember the first time my daughter rode Small world all the way through without falling asleep. We used to get in line and she'd be wide awake, but as soon as we would get to the boat she'd be out. Finally she made it on the ride. Another time riding small world, I watched as for the first time, she actually turned her head to get a longer glimpse of something on the ride, instead of just watching the ride go by.
At 2 years old, you could ask my daughter what level of the parking structure we had parked on and she would tell you, even when the adults couldn't remember. In fact we were just there on Saturday, and my 5 year old had to tell Aunt Karen as she was leaving exactly where she parked (Mickey 2D) because Aunt Karen couldn't remember. My daughter was right.
We she was 3 we took her to Disney World, (which she calls the other Disneyland). 2 weeks ago she picked up a set of WDW maps we have at home. She looked through them all then stopped and held one out. She says Mommy we didn't go here. I looked at what she had and said. Yes we did, that was the park where we saw the Little Mermaid movie, and saw Playhouse Disney, and where you rode Tower of Terror (her idea not mine). She says I know, but we didn't go here, and points to a specific place on the map. She was pointing to catastrophy canyon. I said you're right, we didn't go there because that ride wasn't working when we were there.
That was 2 years ago, and she could pick out the one ride on the map we didn't go to.
We've taken our daughter lots of places, museums, zoos, amusement parks, etc. When she was little, we'd just stick her in the stroller and off we'd go. Most people tell you to take breaks, and if that works for your kids great. We just kept on going and let her sleep whenever she got so worn out she fell asleep.
When Lindsay was 1 1/2 we met up with a bunch of people whose kids were born the same time as Lindsay. One day we all went to the zoo. After lunch we all split up, and all the other parents went in search of somewhere quite so there children could take a nap. We on the otherhand decided we would continue checking out the animals and walk the zoo. Lindsay was the first one asleep. When we met up, almost all the other kids hadn't taken a nap, and those that did had taken awhile. The kids were so wound up with so much to see that when forced to quitely lay down for a nap they didn't want to. We just left our daughter in the stroller and she calmed herself down enough to fall asleep. This strategy may not work for everyone, but it always worked well for us.
