Have been to Vegas 30+ times and have done pretty much everything. Not an expert but here are my top 5 non gambling things to do.
5. Pool- probably not a huge scene at the Orleans but the pool scene in Vegas is always nice. Usually good sun, good scenery and good service. There's usually a party side or time and a relaxed side/time so choose wisely.
4. Hoover Damn- pretty cool and massive piece of American History. It's a decent drive out there but if you're on the strip for a few days it's worth it to get away. Make sure and do the actual tour so you can go inside and see the turbines etc.
3. Golf- I'm a golfer so this may not pertain to you but Vegas has some pretty good courses and I love desert golf.
2. Desert Dune Buggies- we had a company come and pick us up at our hotel, drive us out to the desert and we rode dune buggies for 3 hours. It sounded very touristy to me before we did it but it was awesome! And this from someone who grew up on go carts, dirt bikes and motorcycles.
1b - food. Never had a bad meal. Have had ok meals but never a bad one and plenty of great ones. Doesn't have to be expensive either.
1. People watching- my by far favorite memory of Vegas is my wife and I just casually grabbing a table at the piano bar near the Bellagio entrance around noon and not leaving until midnight drunk off our ass. Just sat there, drank, listened to the piano, watched hookers and Johns, random people, couples fight, degenerates moping etc. just a world class place to people watch.
If all else fails just drink and walk the strip!
