Ishi, the show runs from Friday through Sunday afternoon. The first hour on Friday usually offers a 10% discount for the first hour only, then regular show prices. Saturday is a great day to be at the trough for the "feeding frenzies", usually every two hours. Later on after the show closes for the day, Busse rents out the Jocks & Jills restaurant for a nice buffet style meal, then the fun begins! Inductions, and you never know what else Jerry might come up with. Then in the patio area are games/contests for shop credit prizes and socializing with fellow Dogs, Rats, and Hogs. You DON'T want to miss it...LOTS of fun!
There's a LOT of hotels/motels near the Cobb Galleria to choose from. I usually go cheap and stay at the Extended Stay Homestead motel, about 1 mile or so from the Cobb
Galleria. I would rather spend my money on knives than a motel room I won't see much of!

It's also about 1/3 the cost of the Rennaisance Waverly next to the Galleria. Just Google Smyrna Georgia hotels and motels or Atlanta hotels/motels for location, cost, etc.
It really is a great experience that every knife afficianado should attend at least once in their life!
I should add that the Cobb Galleria is way in the northwest corner of the Atlanta area, practically in Marietta. Nicest place to be for Atlanta!
