Start contacting ladies right NOW!  A lot of the top Vegas escorts book in advance and may not have time. Since you've not written any reviews, I have no way of knowing your experience level, so  make sure you have references. The best ladies will want to screen you for their safety.
Finally, take a look at the top 100 list for Vegas, it's a good place to start your search, but you'll need to be VIP to get the most out of the reviews.

I'll be visiting Sin City this week! Partially for business, but always looking to have fun! Running on a tight schedule which makes my times not so flexible and that sucks, but once I arrive I should be able to organize my time properly.

Anyways, just figured I'd look around on TER and see what Vegas has to offer. Outcall to my room on the Strip would be ideal. Any tips or suggestions? Can't wait to get in to town and have a blast! Vegas always treats me right
