Your using my name again as if I really know whats going on....ha ha
Anyway, if your visitng Las Vegas you have options other than LAS(McCarran Intl). If your in a Lear or above , by all means LAS. Thats a busy airport and yes they will give you service but I think you may be happier at either North Las Vegas VGT or Henderson L15. Its sort of the place us little guys go too....
Call ahead and you can make all the necessary arrangements. Casinos will pick you up if you have the right one....
Make sure you have full knowledge of the Class B airspace as its very important in this day and age. Screwups cost you money, which can be the least of your problems..
ATC is very helpful, just be patient....
Email is good if you need further....
