Wondering about what you guys offer for overnights or short trips in ppm.
I wouldn't think the gal sleeping over and leaving the next morning would get anything extra, butwhat about a one-day trip to the beach or somewhere? I was thinking 1.5x ppm for a trip with one night and 2x for two nights, but interested to hear what others have done.

I haven't done many, but you're right about one thing.  If it's sleep over and leave the next morning, just the normal ppm.  If she spends the night and there's more than the usual amount of bcd activity, 1.5x-2.0x has worked for me.  Gas money is a separate issue if she has to drive some distance.

Several SB's have stayed overnight before. I didn't pay them extras since we only did it once. At my age, I need more than a night of sleep to recover so I don't have the sex drive to do it again after I get up in the morning. I can get hard again but just don't feel like doing it again in such a short time. It's like having a nice big meal and don't feel like eating again so soon.

I've never paid more for overnight than the amount I would pay for a regular date that includes BCD. I encourage overnight ("Bring your overnight bag. "   when my schedule permits. Channeling Tomcat, I don't have the drive I once did. Multiple pops take at least two hours and that's if she's very hot and I haven't drunk very much. So overnights work well because I regain the desire and ability to perform again in the morning. One girl, a late sleeper, even said I had converted her to a lover of morning sex.

 
Regarding trips, each time I've brought a girl on a trip (meaning, she flies to whatever city I'm visiting), it's usually been just one night. Occasionally two nights if I know her well. Still, I've only paid the regular date rate plus airfare. Maybe I'm cheap? They never asked and they never seemed put off by the regular amount since they saw me again.
