I stayed there about 8 years ago. It was fine, but it may have slid since my visit.
One drawback: The shuttle bus to Disney. Luckily, Days Inn was (at that time) one of the first stops so you could get on and get a seat. But then we stopped at a dozen other hotels in the same area before heading to the parks. By the last hotel stop people were pracitcially hanging out the windows we were so jam packed! The shuttle only had a couple of pick-ups in the AM and a few return runs in the PM. they may have changed their shuttle since then, but at the low prices they offer, probably not. We found it easier to walk to Downtown Disney and take a Disney bus to a park from there after breakfast at DD. Not a good plan for large families.
One plus: It is pracitcally adjacent to the Goodings plaza and lots of food and shopping options (taco bell, red lobster, mcdonalds, TGIFridays, not sure what else)
priceline or hotwire are decent bets if you check sites like betterbidding and have a ballpark idea of what you may get and aren't too picky.
good luck!
