OK - who has been there, where do you recommend to stay, what do you recommend to do? My wife & I (late 20s/early 30s & no kids) have never been to vegas before, we figure we will be there for 3 days & the weekend. Hope to stay on the strip itself (hey, why not, it is vegas), but are open to doing things off the strip (maybe grand canyon helicopter tour, etc). Your recommendations/suggestions/comments please!
