I think you will be fine. It is right across the street from Bellagio and it is on the strip. It has everything you need for your breakfast and snacks and the extra space should be welcome. Reviews on Tripadvisor look promising.

I am not sure about the rental car in Vegas. I guess I would check the rate including the taxes,etc. If you plan on shopping at the outlet malls, or leaving the strip area, then I would consider a car.

Where do you live? Driving on the strip can be challenging because of the traffic. it is sometimes hard to figure out how to get into the different casinos and you might drive by the entrance because it is not well marked.

We drive from So Cal and we don't normally move the car once we arrive. We either walk or cab it but everyone has different needs and with a 6 year old, I might think about one.

I think you'll be okay at the Polo Towers, although I remember hearing that two people who stayed there last fall contacted Legionnaire's Disease. I know there's a Walgreens on the strip fairly close by where you could buy a cheapo coffee maker, then just give it to someone or leave it in the room when you leave. Totally agree with you--they're great for heating up soup, etc., especially with a little one.

There's a M and M store on your end of the strip that has an interactive tour--perfect for a 6 year old. Of course, like all good tours, it ends in a gift shop filled with you know what!

ltr, we live in Germany, just moved here in August. One of the great things about it is NO need for a car. I really hope not to have to rent one, especially when I'm dealing with jetlag and time deadlines in a 'new' city.
Dancing Bear, thanks for the article link.

Wow! are are traveling a long way for AAG. How lucky to be living in Germany. It is one of my favorite places to visit. Are you presenting at the conference?

Since you will be suffering from jet lag And traveling with a six year old, I would not get a rental car. A little walk in the fresh air coupled with cabs and shuttles should work well. You can always get a car once you arrive if you change your mind.
