We stopped in Savannah too!
Both times we stayed at exit 94. We felt safe, there were plenty of eating choices, and the hotels were right off of 95.
On the way down, we were staying on Mariott points and stayed at SpringHill Suites, which was very nice, spacious, and had a nice breakfast.
On the way back, we didnt have points and stayed at Country Inn and Suites at the same exit. It was roomy, had an indoor pool and free breakfast. It was not as nice as the SpringHill suites, but it was safe and clean.
