The conditions you have described are pretty typical for North America. The minimum bets you describe are also somewhat typical. In Vegas, minimums are $10-25 per spin depending on the casino, so the minimums you are describing are not that out of line for a casino with 6-8 wheels.
Additionally, the problem of no one betting after the spin is also not uncommon for North America. I am in Canada and it's pretty much the same deal here. However, there are ways around it. Just as there are also ways to make them call NMB's a little later.
I had to deal with this myself when I got into VB. The problem you are going to be dealing with primarily is the issue of bankroll fluctuation with a high min bet. I'm guessing if you are like me, you'd much rather a $5 dollar min bet rather than a $20 if you are just fooling around with VB/starting out. Good news is there are solutions to all the problems you are describing and they are pretty simple. (PM me if interested)
The best part you have going for you is the number of wheels in a casino. My casinos tend to have just one wheel. Some have 2, or 3 live wheels at the most. So picking ideal gaming conditions can be a pain in the butt because it usually involves changing casinos. Smaller casinos, if they exist in your area, may have lower limits, but fewer wheels. So it's a matter of preference.
