It depends how important is to you to save $$ vs. staying at a Disney hotel. You definitely won't get a Disney hotel for $77, but I saved $100 for a 4-night package with DC staying at Grand Californian. There was also a special at the time where we got a 4-night stay for the price of 3, and we paid about $1100 for a theme park view, including 4 day hoppers (for the price of 3-day hoppers), a character breakfast, and $20 in ESPN game cards.
We also got 10% off all purchases of $50 or more (which we used at least 3 times during our stay), and 1/2 off the Walk in Walt's Footstep's Tour ($16 per person, regular price).
For us, it was worth the renewal. (Plus, you get a subscription for Disney Magazine, which I think normally runs about $16 per year).
