Your best bet is to do everything separately, and not use a "package" with any company. That's not a real crowded time, so it shouldn't be a problem. Check with the websites of any hotels you want to stay at for their best prices. I've hardly ever found a better deal on expedia or travelocity than the hotel's own website. Then call the hotel directly, tell them what the website says, and see if they have anything better (through a
AAA discount, etc.) Check tripadvisor.com and mouseplanet.com for hotel reviews. I'd recommend the walking distance motels along Harbor for the best location. That way you can walk to the parks without having to pay for parking.
You can get tickets through
www.ARESTravel.com for a bit cheaper than the Disney website. Also, many credit unions and employee unions sell tickets. My husband works for a government lab, and we can always get park hoppers WAY cheaper than at the gate or through the Disney website.
If you want any advanced dining reservations, just call and see if they are still available. If not, just show up at the restaurant you want right at opening time for the meal you want, and there's usually room.
I'll bet even at the last minute, you'll do a lot better than many who've planned for months ahead and gotten a package from Disney!
Good luck!
