Which lens should I purchase for my Grand Canyon hike?

The Nikon 12-24 doesn't have a lot of great reviews. Cost too much and doesn't perform accordingly. Would an 18-55 get me decent photos? Or should I go a bit wider? I would like a lens that is versatile (weddings, portraits, indoors, etc). The Nikkor 18-55 only goes to an F-Stop of 3.5. Is that enough for indoors? The Tamron 18-200 doesn't have great reviews either. What about Sigma 10-20? Is that too wide? Would I get use out of it after the trip?
