There's a fairly new Hamtpon Inn adjacent to the parking lot of Hamilton Place Mall and a brand new Aloft by Marriott, probably been open 3, 4 months right in the parking lot of the mall. Never even understood why they'd built a hotel in the parking lot of the mall but they did
The issue can be accessing them. From 24 it's easier, you take 75 north and take the Hamilton Place Mall exit and it dumps you right there by them. Then you get right back on 75 South right where you got off. If you are coming from 75 going south it's harder to get to since you have to get off on Shallowford and work your way to the mall parking lot, through very congested roads
Good news is they've finished the redo of the 24/75 split so that flows much better than it used to, with much less slow down and accidents.
If you want to avoid back tracking even a few miles they've been adding a lot in East Ridge, on the East side of 75, where the Bass Pro Shop is, near Camp Jordan. I'd avoid anything on the West side personally. There's a pretty new Hampton Inn on the East side. Several new restaurants too.
