The appeal of multi-day dates and trips with providers

I don't think you should look at a multi-day date/trip as purely about sex. It's more about companionship and spending time with with someone. If all you're looking for is a number of specific "acts" then you're absolutely correct - better value in multiple disparate encounters. If on the other hand you want time with a hottie that includes intimacy and companionship along with sex, then the multi-day trip could serve well.

You probably don't want to do to a multi-day with a provider that you haven't built a rapport and connection with before the trip. You'll be with her for an extended period of time, not all of which will be sex. You need to be sure that you AND her are comfortable with the extended time together which will include sleeping, eating, sharing a bathroom, going out for meals and/or entertainment, recreational activities and other activities outside the bedroom.

I have done this with a provider in the past. It was someone I had seen many times before and we'd built a decent rapport. She didn't charge me the excessive overnight rates that most SPs charge, in fact we didn't really discuss the economics of the trip, she just tagged along and met me during a trip(s) (we actually did this twice). The first time was a great time and we both had a lot of fun and thoroughly enjoyed a few days in the sun. The second time was a disaster. I think she wasn't in a good place and this surfaced on the trip. This made our remaining time really challenging. I don't think I'll be doing this again...

So while there is a place for the multi-day trips, I think it really boils down to what you're looking for. If you're simply looking to scratch the itch, then multiple short, no strings attached hour or two sessions will fit the bill. If you're looking for longer intimate engagement, then the multi-day option is there, but it's a large commitment, financially, emotionally and time. Make sure you're ready for the "commitment" before indulging...

The other side of it is the fly me to you experience.
You can have (pricey) fun with an indie that appeals to you for a shortish duration playtime.
And know she will not be texting you to try to drum up another date like if she is in the same city/area as you are.

And if you want, the fly to you does not require for you to be at your home base either.
