One of the great areas only a couple miles away is Downtown Disney - which has a ton of great things to do - day and night:

Another awesome place a mile away is Old Town.

The classic car shows at night are awesome and just the whole place is fun!
One negative of I-Drive is the conjestion at night. You can't even move sometimes... this area has more room, that is for sure!
