No, I get why she didn't spin a second time. I must not have explained it clearly. If she's so sure about the solution, while picking the letter on her first and only spin, why didn't she pick a letter that would get her a little more money? If she had picked "T" instead, she walks away with the trip and $2700, instead of just $900. I'll stick with the thought that taking "L" proves to her that the first word isn't "I'll" and that her guess is safe.
