If it's Monday, and I am looking for something for the weekend, 24 hours is fine. I'd even give her all day Tuesday and look for a reply when I wake up Wednesday morning.
If it's Monday, and I am looking for something for Tuesday, other variables come in. You say back and forth is happening, and you've been given time options. In that case, if she has told me, for example, "any time between 2PM and 8PM," and I have responded, "I'd like to meet for 1 hour at 2:00." I assume on my end that the appointment is made. She's told you available times, and you have selected one. I'd give her until the end of the day to confirm. If I don't hear back by bedtime, I'd politely email/text again to get a confirmation. If I don't hear back by morning, I assume it's not happening.
Bottom line, I realize she has a life. She goes to movies, goes out to dinner with her mom, takes naps, and has multi-hour appointments with other clients. There's no set time frame. It's more about how far out the desired date is
....I check mail twice a day: early morning, and late afternoon/early evening. When I retire for the evening, I enable my away message to let others know that I will be reading mail in the morning. I do, however, let new friends know when I check mail.
I also enjoy another profession, and the same rule applies. I have a life!
Hugs and Kisses,
Kelly
See Im the other way around. I hop online every 2-3 days which is what I let be known on my eros ads, ad posts, & websites. Calling reaches me right away. As long as you make known what works best for contacting you, there should be no problem. I def prefer phone. Every1 is diff. 
I make it a point to be online and check messages at least a couple times a day., especially if involved in a back and forth discussing an appointment. If I know that I cannot return emails within 24 hours I make sure to put up an automated response email that lets people know when I will be able to check my email again.
We all have personal lives and things do come up, but 24 hours with no response when in the middle of setting up and appointment becomes impolite. I mean, this is a business interaction, after all.

This is for both hobbyists and providers.
If you are discussing appointment times with a provider/client, what is a reasonable response time in your opinion? To be clear, this is not in regards to contacting a provider the first time. Assume that you've offered or been offered days or times and there is a back and forth conversation happening. In today's world of smart phones, how long should one expect to wait to hear from a provider or hobbyist? When does it become impolite?
I have two rule of thumbs I go by....
After initial contact, I like to be responded to me within 48 hrs with one of the following responses..
A) Sure.. I'd love to meet up with you babe
B) No sorry.. We are not a good match
C) Fuck you.. 
The day of the appointment, when I email to confirm it in the morning, lets say, for an afternoon meet up, then I expect to be have my messages returned in 15-20 min.
For those who are busy with personal life, civvie job, or are high volume providers, it pays to hire a booker.. No we don't expect you to respond to emails whilst fucking another John...

I went into session today, came out and had 16 missed calls.
Between calls, voicemails, texts, emails, PMs, Preferred411 mail, fuckin' Twitter DMs- omg ! LOL
It gets outrageous!
You must consider than an independent who works without assistance must not only field volumes of communication and suss out legitimate inquiries from nonsense, she must schedule, play and take care of her known guests via friendly communication to let her best guys know she's always thinking of them.
I think that 24-72 hours is completely reasonable turnaround time. If your schedule doesn't allow you to plan appointments in advance that is perfectly fine....but sometimes I'm really taken aback by clients who expect & even demand that their communications be returned immediately for their last minute / same day appointment requests.
Per your scenario though-I think that if a client and provider have already established contact and mutual interest in meeting confirmation of appointments to occur within 24 hours should be rather quick- back and forth vollying, both should be paying attention to their email/PM/IM whatever in anticipation of tying down loose ends.
I think that if an appointment is scheduled a few to several days/weeks out there should be less pressure but reasonable attentiveness.
If a client is contacting me attempting to coordinate say, an outcall during his business travel a week in advance I want to know that I must carve out his window of time, but when he contacts me and asks for the time I've already put it on my calendar in pencil so there is no sense of pressure or urgency until closer in.
I think everyone should approach these things with respect for the others time & interest....but also with mutual understanding & patience.

You probably wore out your welcome.

They are easy to hack into & def dont access my email/profiles from the phone I use. It's solely for calls(Oh & Twitter/Instagram)
So there is that 2 consider.
There are a lot of variables... I don't have an assistant, so I must manage my provider time, real life time, other Job time carefully! I don't answer a lot of weekends because I am with family a lot. If I am touring, I try to stay busy and I spend most of my time emailing with clients I am seeing on that tour. Future dates have to wait a little longer for replies.
However, I always offer an apology if I am a little late with an short explanation. Most guys seem to appreciate that and understand...
As an example, I am coming to DC/NOVA is a couple of weeks. However, I am home this week and with it being Thanksgiving week, I will be very busy with real life!! So, my replies will be slow. But I will reply!
Smooch!
