Other ways to get lower rates:
Buy an Annual Pass, call the Disney owned hotels directly and ask for any AP rates. In the past at slow times of the year they have awesome AP rates of $99 for
Disneyland Hotel week nights (more on weekends).
Otherwise they offer a standard 10 % off rack rate (same as you would likely get for AAA rates)
Stay off site..
Personally I found that staying on site was fun but not necessary. Some off site hotels are closer to DL gates than on site hotel!
Check around online for rates (use Travel Axe or Side Step to find multiple deals) - check each hotel's own site for even better deals.
Call hotel directly and ask if they have Entertainment rate for your dates. I typically pay $45 a night for Hojo's (very nice hotel - very popular and just 10 minute walk to gates).
Be courageous: Try Priceline (go to
www.biddingfortravel.com for great tips and see what hotels are popping up for winning bids). Try Hotwire (lots of people get the Hyatt for $39 a night)
