Except for short periods of time when I'm trying to get the stage dancer's attention, or waiting to tip the dancer on stage, you will not find me stage side. When you sit at the stage, you are pretty much obligated to keep the George's flowing. It's a waste of money, unless you truly have an interest in the current dancer.
Typically, when I walk in to a club, I will place myself where I have a good view of the stage, and somewhere in the middle between the stage and the wall. Ideally, someplace where I can also monitor the private dance area - or at least the VIP doorway. Gotta see who is popular, and who does multiple dances (don't want to pick a girl that is a one dance wonder - not enough mileage to warrant more than a few dances).
When at BBF, I usually sit at one of the upper level tables, close to a stair way so that I can quickly make my way to the stage if the stage act gets my attention. It also lets me take a dancer back to the private dance area and/or VIP easily, without having to zig-zag my way between tables with girl in tow.
Since I have more experience at HH than any other club, the following might be helpful to anyone going there;
When at HH, I almost always get the same exact table - I get there before the crowds hit, so it's pretty likely to be open. If not, I sit as close to it as possible and keep moving to closer tables as they open up, until I get to my preferred table. Looking at the stage, I sit at the table located off the left corner, two rows back - on the aisle near the old bar. From this table you can see who is arriving and departing at the club entrance, you can look down the hall to the back door exit. There's also a great sight line to the small dressing room / girls bathroom that a lot of dancers pop into to freshen their hair and makeup, and perform necessary outfit adjustments (NOTE: you often can see more flesh in that room than you see on the dance floor, if you keep an eye open). Also, the walkway from the bar (the office is behind the door in the bar) to the floor is immediately behind you and dancers congregate there. You also have an excellent view of The Wall area so you can monitor the mileage going on, and more importantly a perfect view of The Love Corner (the one opposite the TV, and the darkest spot for getting ultra mileage). As a bonus, you can see who is coming up behind you by watching the reflection in the mirror on the back wall of the stage. You are also strategically placed to grab the attention of dancers getting on / off the stage, and arriving / departing The Wall area. This table is probably the highest traffic area in the whole place. Once I have a hottie picked out for some private chat / dance / play time, I usually take her and my drink to one of the tables adjacent to The Love Corner for more darkness and privacy. From that table it's very easy to watch when the Love Corner is available and to quickly grab it before the next fun-loving couple sits down.
