Re: Favorite Place in Vegas *LINK*
Downtown is great because it is like a big shopping mall of casinos. This means that they have to stay competitive (to a degree) since people can walk 10 yards down and be at the door of another casino. It also means that you can marvel at the spectacular "wall-to-wall lights and sights."
Like the Mayor said, conditions change from day-to-day and shift-to-shift. Your best bet is to just walk up and down Fremont St. and walk through EVERY casino there. Stick your head in and see what games they offer and what kind of penetration you can get. Since it is your first time there, you will want to see all of the sights anyway!
It's also a good idea to have a "bible" with you on your trip. Before every trip I always go to Trackjack and print a copy of the conditions (rules, table limits, average pen) at all the casinos there. Then I will go through and mark the ones I want to visit and why (maybe because they have good rules, good pen, low limits, lots of tables, or whatever reason). This way you can have a good idea of where to check first, and you can also know the house edges when you walk into any other casinos.
If you don't want to pay for Trackjack, check out

Give us a full report when you get back!
