Most of the girls at Diva's provide; some live near by; others will go with you to your hotel if that's where your staying.

Some of the Darlings provide, but not all.  You can find out by asking or getting a lap dance (assuming that's still going on on the top floor)

Hi,
 As one who has visited the club several times the answer is as follows. All kinds of women visit the place so don't assume they are all providers. Some are and they'll let you know. The darlings are for the most part just dancers who come there to earn money for their dancing only and are not providers. Come on in some night after 11pm and check it out. You'll have your best luck on the weekend.
