I went on a family trip last October and we saw Love. I'm not a huge Beatles fan, but I really enjoyed this (my second time in maybe 6 years). If you're not big on Cirque's clowns, this one is relatively minimal. The theatre was about 75% full, so I bet it's on TodayTix or at those Tix4Tonight booths. (One of my relatives treated us, and I'm not sure where he got them.)
If you want to venture off-Strip, head to District One in Chinatown and get some amazing Vietnamese food.
