QUESTION 1: I use both options, same-day and in-advance arrangements, it's situational for me.
My Romper Room (by choice*) is the city of Tijuana in Mexico, even though I live on the US side of the border. I have to plan my mongering with the precision of a military mission, taking into account days times of availability of the provider(s) I want to see, flakiness, currency exchange rates, traffic, transportation, waiting times to both enter and leave Mexico (always an unknown entity), unexpected hassles, my cover story, all kinds of things. Imagine a provider being late, a no-call/no-show, a bait-and-switch, or no vacancy at the No-Tell Motel, a "4-star" hotel actually turning out to be a minus 2-star roach motel, (all very common occurrences in Tijuana).
In the beginning of my mongering years ago, I had to abort plenty of missions and return to CONUS (the Continental United States) with a red face, white anger, and blue balls. Nothing is worse than going through all the trouble of forming an alibi to get away from The Warden, sneaking southbound under the radar into a foreign country, trying to get my pud pounded, get left at the altar with the twins still bulging with white sauce, wasting an hour crossing back over the borde northbound, and slinking back to home plate not knowing if I've already been discovered. To fertilize the tonsils or the belly of some Latina Lass makes all of that worth it, so I learned the hard way to always go there with a Plan B, C, and D.
As such, same-day can sometimes be sketchy, so I often start my phone calls from several hours up to a week in advance of the moment that I expect to hear the klick-klack-klack of high-heeled shoes approaching the door.
One part of the back-up plans is my long list of luscious lovelies I can call at a moment's notice once I'm already in a hotel room and Plan A has flopped or if it's an incall and she cancels, if I'm standing outside of a taxi whose driver has the gearshift ready to go from park to drive and move that right foot from brake pedal to accelerator.
There have been some occasions where the urge and the opportunity to go south of the border to get laid happened to fall into place all of a sudden, so same-day or last-minute were the only ways to go.
QUESTION 2: In Tijuana, especially with everything that I wrote above, 1 hour is my basic timetable, 90 minutes is a luxury every now and then, and a couple of times I hit the Daily Double of 2 hours, but those were pre-Corona Virus. My exercise regimen and overall lifestyle have blessed me with the virility and stamina of men half my age (which is part of the reason I'm a hobbyist; it was all going to waste), so I offer stud services for as long as the lady can stay on the bronco.
*Some nutcase ragged on me not long ago about saying that I hobby in Tijuana. He went on and on about how if I didn't like it I shouldn't go there. He missed the point entirely. When I comment on the ups and/or downs of going to Tijuana to get laid, I'm passing information, which I thought was the main point of this website. Others who are interested can use a compilation of information about it to either make their own decisions as to do it or not, or it can be a comparative feature to other options, or it can be a confirming feature for those who don't want to select it. I've learned A LOT about hobbying from this website, once again, that's its purpose, and I wish I had known even 10 percent of it in the years and years I hobbied alone before finding this place. (I started her about 60 days ago as a VIP.) If I can help out by passing on tips from my tales, I hope someone finds them useful.
I go to Tijuana by personal choice, I enjoy all of its positives, I tolerate or try to mitigate all of its negatives.
