On more than one occasion, I have ...
This is similar to what I do.
Unless it's not possible due to the Hotel security arrangements, I always have the girl come to the room. I love the feeling of anticipation and getting the knock on the door.
A room with a Hotel Safe is a requirement! I keep excess cash and valuables there, so if something gets robbed (never happened so far) it won't turn my trip into a disaster. I keep the agreed amount for the punt on a side table in plain view, and cash is fanned so it can be easily counted at a glance. In case I wish to add on extras I keep various note denominations hidden in different places, e.g. a €50 note under the mattress, a €20 note under the mousepad and a €10 in the cupboard. I don't want the escort to know how much cash I have on hand in total, nor where I keep it 🤐
In terms of drinks and snacks, I start by getting rid of the Mini Bar stock, and hiding it somewhere.
Then I stock the fridge with my own better quality stuff. A selection of beers for me, some sparkling wine for her. Plenty of juices and mineral water too, both still and sparkling. Most escorts won't drink while working (for obvious reasons), or if they do they'll have one glass, maybe two if it's a long booking, so I try to get the smaller sized bottles of sparkling wine, as I don't drink it myself, only beer.
In terms of food I usually go with Sushi, however I have crisps and chocolates around too. Since I only do outcalls when travelling, I ensure that I get confections from the Airport that are not available where I'm travelling to. Sushi is great because you can get it ahead of time without worrying about the temperature, just keep it covered and in the fridge, and if she doesn't want any it'll keep nicely for you to eat later. An added bonus is that most escorts I've encountered can't use chopsticks, so you can teach them as a kind of icebreaker, and I find that feeding each other with chopsticks is rather sensual.
Have some mouthwash handy too, if you're drinking beer, you don't want beer breath hampering your DFK experience, nor do you want any strong tasting food from her side lingering either.
By creating a nice atmosphere and environment, I've done everything I can to set the stage for a relaxed punt, the rest is up to her. So far this strategy has paid dividends in spades. Nearly every Indie that has visited, has overstayed by quite some margin, and a few agency girls left me their private number so I could book them for a return visit without the clock running.
I have no problem spending an extra quid or two to get the most out of an outcall. You'll be eating the same snacks and drinking the drink too, so why not get stuff you yourself like.
