I will be coming to Vegas for business, and not entirely sure what my schedule will be from night to night.  So, wondering if I should try to book an appointment in advance with an Indy, or just call an agency when I know I am free?  

...when its busy, booking in advance is always best so you are not disappointed I also welcome last minute appointments if I am free.  If you think you would like to use an agency you would be very happy with 100Proof....and they even have a sexy new Asian girl who is getting great reviews

Choose the ladies you are interested in and ask if they would be willing to pre-screen you since you are not sure on your schedule.
That way when you do have some availability on your schedule it will be easier to set an appt.
Especially if you are a P411 or date-check member
I find that works best for me depending on if my schedule will allow.
Or you can try an agency as well do what works for you

I welcome last minute appointments if I'm available

PS. I am cool with that too.... I understand the need for flexibility...

I agree with Jaydalee. And I take last minute appointments if available. Just require couple of hours notice to get ready and get to you.

Thanks.  I usually do pre-screen, and nice to hear that so many ladies do not mind last minute if they are available.  I had noticed the ladies from 100Proof, so will keep that option in mind too.  In the past, it has usually been flight delays that cause havoc with best laid plans.

then out can set the date/time as needed but you got the screening out of the way!

I am totally on board with pre-screening.  I always try to do this - but is it OK if you ask a few ladies to pre-screen you?  I mean, one lady may get busy and not be available, so it would be nice to have a few that may be able to see me, right?  If so, is there a good way to say, sorry - I have decided to see someone else?
