Hi! When we planned our trip to Disney, I was advised not to stay at any Days Inn in Orlando because it's gone down, also I was told by 4 people not to stay at Travel Lodge Maingate However, on the positive, we highly recommend Holdiay Inn Family Suites! We just returned, it's a nice hotel with great accomodations. We also got a good rate.
Good Luck!

Knights Inn is worse than you can imagine (entire chain is rated dead last) by Consumers Reports.
If you post your budget and how many (and ages) of your family I'm sure you'll get some specific suggestions.
