yes some prossies cant read your requirements (or have self delusion on how fit they are) but you will get at least 3 or 4 that are hot and willing to do an overnight booking for 300
First it depends how you define hot and whether the profile pictures of these WGs were indeed genuine (as you just met with only 1 of these 3-4 at the end).
But let me describe my own recent personal experience with overnights. First I don't like reverse bookings (for multiple reasons that I will not state now) but when it comes to overnights I sometimes directly contact the escort and make my overnight offer (e.g £500 overnight).
In particular this July and August I booked in total 8 different London escorts for outcall overnights in local hotels. I was personally targeting good escorts (i.e. beautiful with good feedback) whose incall overnight rate is £700 and the outcall rate is £750-£800. I totally sent text messages/emails to about 30 (of whom I selected the 7, the other one being Cassie Alex mentioned above who charges just £400) asking them whether they could offer a 10h outcall overnight for £500-£550. The vast majority of them replied that they would be happy to do it for £600. Only one of them accepted 10h for £500 while there were very few who replied that for £500 they could only do 5-6h (22:00-03:00 or 22:00-04:00). Anyway I didn’t want to negotiate the price. It was more like making an offer (as in the reverse booking) rather than asking for a discount. So I was happy with their anti-proposal of £600. As I said during the aforementioned period I did a total of 8 outcall overnights, 7 for £600 for 10h (instead of the normal £750-£800) and 1 with Cassie Alex with £400 (her normal rate) for 8h.
The service was always good and the discount didn't affect the willingness or the performance of the escort. Almost always there was a 4 hour sleep (girls’ demand as I could virtually go non-stop). Thus 6 active hours, which effectively means £100 per active hour. The bottom line is that for overnights most escorts charge at least their active hours (at their normal hourly rates -or slightly less like £100 instead of £120).
Be very careful with overnight offers for less than £500. It may turn out to be a 6 hour sleep. And this actually happened to me two years ago where I paid £450 for a 9h booking (21:00-06:00) and the girl slept very heavily for 6 hours! (23:00-05:00), as she came to the booking very tired after working all day. Basically I let her sleep as she was indeed very tired with the intention to wake her up at 03:00 but the bitch was virtually dead when I attempted to wake her up (at 03:00) so I gave up and attempted again at 04:50. Thus best always ask how much sleep the escort expects to have before making any overnight booking. A £300 overnight might turn out to be just a 2(-3) sex rounds.
