Hi Ron,
I agree with Don as well. Having a table with one person seems to be optimal.
On the flip side, I have found that a full table can be beneficial in some situations. Like when you want to maintain a low profile (i.e. places you plan to frequent), or run down an unfavorable shoe a bit faster. In cases when things ARE favorable, you can hide your spread behind other players which would have a better chance of going unnoticed (if that's an option).
Hope that helps!
