I haven't sugared in Vegas for several years. But you should expect to see mostly UTR (or maybe not UTR) hookers if they are located near the Strip. This is not necessarily bad... but hookers using Seeking will mostly be using it to find new Johns, hopefully under less scrutiny than they might see using traditional web ads.
Still there are a significant number of profiles from young college students, out of state vacationing babes trying to live out a fantasy, and local Vegas residents who are looking to supplement their minimum-wage, low tip jobs off the strip.
How can you tell? There's no guarantees. But generally, UTR hookers will use the same pics they use on their ads - typically professionally shot for mid to upper-class providers. While locals and vacation fantasy POT's will use selfies, especially bathroom selfies, and even more especially selfies in popular Strip locations.
Once messaging off the seeking site, UTR hookers will generally quote allowance asks in hourly terms and will probably use the term "P4P" as well, In addition they will use other "hooker" terms like a "No List" (i.e.: no Greek, bare, CIM, etc.) or in-call/outcall. Locals & vacation POT's will ask how much you will offer and will not specify a time frame.
UTR hookers will generally be available to meet any time but will push to meet NOW - they want you to make an "impulse buy." They may hint that they will not be available after the next few hours or the next day. Vacation POT's will generally want to meet or vid chat 1st before committing to BCD, and they will need to work around the vacation schedules of their travel partners - usually other women, but that MAY be a BF or Hubby. Locas will probably have a day job, so will want to meet off work hours.
If you are only in Vegas for only 2-3 days, you may be better off just hiring a pro or a freelancer from Strip Hotel bars or the hotel crosswalks after 11:00 pm to about 5:00 am. Scheduling a M&G with multiple POT's (2 or 3 a day?) then closing at least one or more to BCD (maybe 1 or 2 a day?) may take more time than you have.
Finally, PPM rates will depend on the factors above, with UTR hookers in the $400-$1000 range, and locals & vacation POTs in the $250-$600 range.
Just remember: She has the power to say "yes," but you have the power to say "no." Do not under ANY circumstances send cash in advance or pay upon arrival. You will lose your money forever, which is not the way you want to get fucked in Vegas.
Life is good
