Tried out SA for a few days
I found that very few of them were interested in short / one night arrangements. These are girls who want $1000 for a night, or even $100 just to go to dinner with you, and nothing else. The few I found who were interested in shorter arrangements couldn't host, lived in BFE, or in one case, I went over to her place, and she had a dog who apparently likes to bite people, so I BTFO of there; I've been bitten a couple times by dogs, it's not my particular fetish. The best offer I got was from a cute chubby girl who said she'd spend the weekend with me for $1500, in a hotel I was paying for, plus meals, plus shopping trips, plus who knows what else she wanted.
So, unless you have $1K to spend for a night, or want to pay a moderately attractive woman $1500 for a weekend (plus expenses), SA probably isn't for you.
