Tell her she gets a free trip to Hawaii, pay for her drinks & food & buy her something nice.
But laying out $4k over and above the trip expenses is insane.
Yip. She is getting a free trip to Hawaii, in winter. You likely could have low-balled her and gotten a much lower rate.
That said, unless you are able to stay up until 4AM at the clubs, drinking the whole time, the little darling is going to be bored out of her skull after the excitement of being in Hawaii wears off, call it day 3. I hope she's a good actress. My money says you will be wishing you either travelled with someone your own age, or had gone alone and just gotten local ladies to take care of your dating and nighttime needs. All the best though!
There was a 50+ Asian guy with a 23-ish white girl last time I was in Vegas. They sat beside us at the Crazy Girls show. She did not look like an SP at all, and was bored to tears, checking her iphone the whole time. I could not figure out if she was on the clock, or if they were a pair of awkward business travelers who were stuck together in Vegas. There was no physical contact that I observed, but who can say. Point is....the poor little lady was bored to tears, didn't smile once. Hopefully you two will click better than they did.
edit. Smylee - you just have to ask the right girl. If a 50 year old guy goes after the 25 year old junior accounts manager at his law firm who just graduated from Western, odds are she'll take a pass. If he goes after the 25 year old hottie lined up outside a club in the entertainment district at 1AM waiting to dance all night long with her girls, odds are she'll take a pass. If he asks the chain-smoking 25 year old welfare mom who has a black eye from her ex-boyfriend, lives in her sisters basement and likes to get loaded at the east end pool hall near her sister's place, he may have a shot at it.
