It seems like as soon as I decide on a hotel to stay at downtown, construction woes seem to follow. I heard about the narrow corridors funneling people around. I plan(ned) on staying at The D and will bounce around between there, GG, GN, Fremont, and Four Queens. A few questions: How bad is the zipline construction around The D? I want to visit The Heart Attack Grill and some of the Fremont East sights, as well as MSS. What problems should I expect?
