You haven't really seen Las Vegas until you've seen The Strip at night. This neon wonderland is the world's greatest sound-and-light show. Begin at Luxor and work your way past the incredible hotels and their attractions. You'll pass the gotta-see-it-to-believe-it New York-New York on your way, and if your strength holds out, you will end at Circus Circus, where live acrobatic acts take place overhead while you gamble. Make plenty of stops en route to take in the Sirens show at Treasure Island, see The Mirage volcano erupt, take a photo of the full moon over the Eiffel Tower, and marvel at the choreographed water-fountain ballet at Bellagio.
