There is so much more to Vegas than Gambling.
The Deuce Bus makes it easy to get around.

There are innumerable taxis in the city and as long as there is not a big convention the wait for one is short.
A trip to Fremont at night is 'interesting' to say the least. I would not go there alone at night, but with a group or a friend it is great. In 2012 we were in Vegas with another couple and had fun there. I did the zip line while the ceiling was doing the light show.
There is more food available than you could imagine. From Buffets to steak houses, and much more. I love the lunch at Estiatorio Milos. It is in the Cosmo and has a wonderful lunch special. Reservations are suggested. The lunch special used it be the year, so this year it would have been $20.19, but it has been 3 years since I was last there and they may have changed their pricing.
Very best tip is to bring comfortable shoes. You will be walking miles. Even if you stay within your Casino you will be walking great distances.
I love people watching and Mon Ami Gabi at the Paris Casino has an outdoor patio. You can watch the Bellagio fountains and the people on the street as you dine. There are not too many places with street facing dining.
I was looking at cheap trips to Vegas for November. Your post is making me think I should look again.
