Spring break may just be the economic tonic Las Vegas resorts are hoping for. The “Review-Journal” says several hotels are luring students to fill rooms and pools before the summer vacation season begins. The Palms is hosting MTV’s annual Spring Break, while several hotels owned by MGM Resorts are offering specials for young people. But police and state gaming regulators are keeping a close eye to make sure those under 21 years old are not gambling or getting into clubs at local casinos. A recent survey by Orbitz.com found Las Vegas to be the second most-popular spring break destination after Orlando, Florida.
