Las Vegas
How much advance notice is typically needed to book a popular provider?
The more notice the better. Its never to early to book. I book until the end of the year and prefer some notice if possible, but I understand its not always an option so I do try and accommodate same day dates when I can

I plan to be in Vegas in November and am interested in booking a provider to secure the date, however don't want to book too far in advance just in case….Recommendations???
I would think its ok with most ladies to book in advance and its not too far seeming as its just a bit more than a month away. Just contact the lady you are interested and ask her if its ok to book now, as long as you are sure about the date/time you want to see her. For me, its never too far in advance.
