I'm already in the Base I'm trying to get renovations in the basement but it says I need to gain her trust
get in trouble with the don and ask to do work for him, he'll ask you to find his pet and will show you a picture of cassie. After talking to her about the don in her base she gets kidnapped and you have to go resuce her, you'll then unlock reservations.
you'll have to make sure you've met fawn and know about her secret job to get help to save her.
