Usually after my delightful hour, I'm looking to get the hello out!  Why not try a 3 hour first?  just a suggestion.  

and they were fine -- but I was also over seas and the pricing was just a little more than what I currently pay for an hour sessions here. These were just over night not over the weekend so might be a bit different that what you're planning.

 
You can also probably find a few threads on these boards with a simple search. The general conclusion I have taken away from those older discussions, and agree with, is don't do this with someone you've not already seen and spent some time with.

 
You also need to think about what your expectations are. If you're thinking about 12 or 24 hour fuck fest, or even just rolling over at any point in the night and getting something started that might not be on the table. Be sure to talk about just what the ground rules will be to be sure your expectations and wants are compatible with what the provider is on board with providing.

thank you I appreciate the feed back everyone,

I would say most of my clients book me for extended stays and ON/weekend appointments. I enjoy taking our time. Can’t speak from a clients POV but I believe it’s mutually enjoyable if I get repeat ON bookings.  
Good luck in your search & enjoy your date!
