+1 - These days the only way I'd consider a 1 hr session is for a first incall meeting before I invite someone to my house for a longer outcall. Definitely can't see the point of anything shorter.
My punts vary between 2-3 hours - for most of my regs the 3rd hour works out £100ph or less so it's usually a no-brainer, especially as I usually have loads of bucket list items / role play ideas / BDSM scenes in mind so there's never a dull moment. 
Yep... I alway view it favourably when girls discount their 2nd & 3rd hours, unless they are already at the 100ph mark with the first one.
