I would walk around the strip. Bellagio fountains and gardens are amazing. there are night shows in many casinos (which are free). If you like hiking there some amazing hiking areas also great for pics. eats there is a lot, I would recommend Wynn buffet, $$ is high but worth it. there is a lion habitat a few miles away. you can also try google, not sure what you are into. Either way I hope your visit is great
