We only stayed here for one night, which is probably the only reason I can give this hotel an average review (rather than a negative one). The bed had the usual comfy sheets and pillows Marriott has recently become known for, but the mattress was hard as a rock. I was pleased that there was a fan in the bathroom (the last two Marriotts I stayed in did not have bathroom fans, which I found a bit annoying), but the light in the shower/toilet room was far too dim. The staff was very friendly, but after we returned from a concert and were chatting in our room as we got ready for bed our phone rang--someone was complaining about us being loud! I can only assume that the walls are about as thick as a dime, considering we didn't have the TV or radio on and weren't yelling or anything.
We were woken up three times the next morning by the same car alarm going off in the parking lot. I know there isn't much that the hotel employees could do about this, but it was frustrating all the same, and that coupled with the hard-as-a-rock bed didn't make for the best night's sleep.
Also, other than the Applebee's next door, be prepared to drive a few miles for any decent food, and don't expect anything in Suwanee to be open before mid-afternoon on a Sunday--we learned that the hard way. As we only stayed here to go to a concert at the nearby Gwinnett Center, we should have just stayed in the Holiday Inn next to the Center.
