I had thought to mention that. As a practitioner of a possession tradition, she'd have experience with this sort of thing and keeping the spirit from breaking the bank. So, I'd reckon that she placed all of her money behind a password protected barrier (bank account or on her phone), but she would have left some amount on the credstick for the spirit's explicit use - probably enough for cover at a few clubs, some grub, and a few drinks. I figure (from Run Faster) that a good meal out is 50, though with all the street food, the spirit could likely have a feast for much less (5 per from Fun Faster). I'd clock cover charge at the 10-20 range, and booze, especially as freely as it's flowing, at 5 or so per serving. I think 100 would be a very generous amount for the spirit to celebrate well in this atmosphere normally.
Of note, though, is that this is more of a wilderness spirit. While he has an interest in (meta) humans, since he is summoned for each new priest/priestess, he does not like to be seen generally. Granted, this is a servant of the Gran Boa (and presumably a servant is summoned in his stead in the initiation ceremonies) which may have a slightly different personality, but I suspect that his interaction would be limited (hence my use of "even" when I mentioned his actually participating). It's a contradiction between this particular loa's personality (hiding and wilderness) and the general rule that loa like to "live it up" while possessing. I chose to go with "living it up" means different things to different loa, and in his case he'd be less likely to interact with people, though with a celebration going on and a body to disguise himself, he might be bolder.
I'll roll a d6 and you can choose the multiplier. Considering the festivities and the spirit's general attitude, I think that 120 is high, but I'm fine with it if you feel its fair. We can say she forgot to secure her newly acquired funds, so that the roll can exceed the money she would normally have set aside for the spirit.
