I've had one duo booking and it was great although both now not working. But what shocked me at the time was the different attitude towards pricing? I had originally tried to book a different duo; one was a girl I'd met already and the other her duo pal. Their rate was essentially their two hourly rates added, but extra if I wanted them to 'interact'. As that was one of the attractions I declined the offer. However the other two girls actually reduced their individual hourly rates on the basis that it was less work for them. So by comparison they were £200 for an hour versus £300. Unfortunately never had a chance to get them back together or else I would have.
