Enjoy!
We've done DL for Thanksgiving the past two years, and it's a lot of fun. Definitely get park hopper, being able to easily walk between parks is amazing. Last year, we park hopped 3 times in one day. "Oh, look, the lines are shorter over in California Adventure... let's just walk over".
If it's your first trip, don't be afraid to check out non-Disney hotels. They are just as close, and a fraction of the price. There's much less magic, IMO, staying in a Disney resort at DL vs World. If I had to quantify it, I'm certain there isn't "hundreds of dollars per night" more magic at the resorts
