Different types of sites require different approaches. Different types of traffic work better with different types of tours too. The comments above hold true in certain instances but won't in others. So to answer your question without knowing site type and if you'll be getting most traffic from TGP/MGS submissions or SE sources, etc... that's tough to do.
But a few things that always help:
1) Make sure the join link is in contrast to everything else on the page(s) and stands out.
2) Make sure the join link appears within the first browser window (without having to scroll down) preferrable at a rez of 800x600 (which means 730x340 for workable space) or 1024x768.
3) Content, content, content. People whip out their credit cards because something they see in the tour gives them a hardon. The text you use and stuff helps but it's more like a little spice added to a good meal. You need the good food more than the spices on top and the good food is what pics and.or vid samples you entice them with. Don't give them enough to whack off to. But give them something they just GOTTA see more of. Then of course make sure that stuff is easy to find in the mem area or your trial conversion will suck ass. =]
Hope ya' find that helpful some. Good luck!
