For the REAL Studio Summit 2011 in Atlanta, finding a hotel seems to be pretty easy. I expect to stay in the conference location, the Holiday Inn Atlanta Airport south. I hope that others will stay there too and we can spend time together for dinners or sit together at the bar.
Of course you make no big mistake if you book the Holiday Inn Atlanta Airport (without south), but you'll have to drive a mile. Next to the conference location, there are at least 3 hotels next door and 20 hotels within a mile.
PS: Seems like the Sleep Inn Atlanta costs less than half compared to the Holiday Inn Atlanta Airport South and it's just a 300 ft walk.
For the REAL Studio Conference 2011 in Essen, Germany, it's a bit trickier. The Unperfekthaus is nice location for events and I really like the room 154 for our conference. But even if they have a hotel part, that is more like an holiday apartment (7 rooms) and too expensive for a normal visit. The best choices may be the Holiday Inn Hotel in Essen, just 350 m away from the Unperfekthaus and my favorite. Hotel Lindenhof may also be a choice and is even closer to the conference location. Finding a hotel is in general not too difficult as as I know there are not other big events which would make hotels a difficult task.
See you there!
