I've achieved all of the following with her: My Super Hero, Red Beaver, Under the Towel, Cum Under the Sun, and Breakfast is Served (more on that below). I've gotten her desire up over 2000, and hotness at 90. On the Saturday to meet her at the club, however, I couldn't find a way to show up there with her. I sent Tracy to the cabin by herself, but there was still no option. What am I missing? Do I need to buy her a dress? I didn't think that was necessary because she had previously mentioned she had a special outfit to show me if I saw her at the club.
Breakfast is Served bug: Once you unlock this achievement, you can replay it every morning. That's part of the reason I was able to get desire so high.
Minor bikini bug: When Tracy is away at the cabin by herself, she still appears back at the house to comment on Lisa's new bikini.
