I typically book dates that are 1.5 to 2 hours long.   I assume longer dates are for enjoying a night out before heading back to the privacy of the room.  Does that include 3 hour dates or is it just for longer dates?

We do the nasty until we are worn out and go eat!  

in North Carolina 4 hours or more....  
I enjoy these days because we have the change to know each other more, have a good dinner, conversation, private time, and a long relax get away.  

If 3 hours, I usually plan on meeting for a drink or two and then BCD time. 4 hours is usually an extended lunch -type date for me. I love clock-free dinner dates... dinner, drinks, and more.  

..... "shorter dates" (under 3hrs) are pretty much for indoors (not that it all has to be hanky panky). However I have done 1hr-2.5 dates that were social/public only (different rate).
