Jack isn't the biggest fan of Fort Frolic, but if you wanted to visit, he'd be happy to take you. He's a tad antsy while there as he’s not exactly sure how to feel about the Splicers and the fact that Sander's still hiding out somewhere around the corner. He doesn't have anywhere specific in mind so he’ll just follow you, one hand stuffed in his jean pocket and the other resting on his pistol. The whole place floods him with uneasiness, especially since his mother's corpse is still hanging around in the back of Eve's Garden. He'd prefer if neither of you had ever gone at all, but he'll push all of his awkwardness aside to see you be excited.
Atlas is a big billiards player, so Sir-Prize is where he'd take you. The two of you could play a casual game of pool, or hit a few of the slot machines, either option works for him. He likes that the place is a lot more down low than others. It's way quieter and tends to house people more similar to him. Besides, Atlas doesn't understand the whole "artist" thing. He'd rather do something than just stare at it.
Andrew Ryan is known for taking people out to Fort Frolic, he loves being able to show off his wealth in such a way. His influence there is subtle but undeniable, and that fact is clearest when he's guiding you down the halls, your hand holding onto his arm as people part to let you both through. He holds you in high regard and would prefer to take you to the classier parts of the area rather than the ones flooded with commoners. He'll escort you straight to the Fleet Hall, a place he personally sponsors, to watch whatever show is playing at the moment. A glass of wine and a box seat somewhere at the top of the theatre, and the two of you will be making the most out of your stay there.
Tenenbaum usually prefers to stay in, but an evening spent at Rapture Records isn't the worst thing in the world. She's never been very attracted to the flashier aspects of the Fort, but the quiet little music shop suits her just fine. She wouldn't mind spending an hour or so in the place, browsing through the options before picking something out and putting it on while you cook dinner together later that night. After Rapture's fall, she'll be even more hesitant to visit the place. She's never been particularly fond of Sander and, unless little sisters are still roaming around, then she has no business visiting.
Steinman adores visiting Eve's Garden. Not even for the strippers, he just likes the romantic aesthetic it has. He's not one to gawk at others while he's out with his partner, but he does like sitting at the bar with you, a bottle of Arcadia Merlot in his hand as you both admire the beauty around you; in the dancers, the atmosphere, each other - He doesn't care, he just loves being out in Rapture with you.
Sander, being the biggest influence, makes sure every little detail is looking perfect for when you come. He'd want nothing less for his muse, a perfect night in the place he holds most dear to himself. Nothing will go wrong and, if it does, he'll deal with it accordingly. His favorite thing to do with you there, he thinks, would be to have you model as he derives inspiration from your poses and expressions. Just be pretty for him and he's certain you'll both have a wonderful night together.
Fontaine hates Fort Frolic. He'll take you anywhere but there. It's much too rowdy and obnoxious for either of you to bother spending time there. Why don't you just come on up to his home and spend a night there? Doesn't that sound so much better? Wouldn't that be so much more enjoyable?
One of the only places Julie likes to spend her time in Fort Frolic is the Gardner Delux Modern. She's not the biggest gambler, drinker, or artist, but she loves going clothes shopping, and this happens to be her favorite spot. She wouldn't even mind paying for the both of you if you decided to take her up there for the evening. She'd be far too ecstatic to browse the aisles to care about cost.
Diane hates going to Fort Frolic. Everything there just reminds her of Ryan and everything he'd ever done to hurt her. She'd much rather go somewhere for the Rapture's lower class. She, ironically, feels much safer in lower-income areas than she does in the wealthier parts of the city.
