In general; extras are available at almost any SC in So. FL except maybe Scarlett’s (although takeout can probably be had there).
As others have stated; Tootsies is probably your best bet – it’s a huge club w/ about 100 dancers on weekend nights (and enough dancers on weeknights).
But Miami clubs are heavily Hispanic – if Latinas are your thing; then Tootsies should fit the bill – if you are looking for more variety of women (i.e. white girls); then you need to hit the clubs in Broward or Palm Beach counties (although Tootsies does have some white girls; but they are a smaller minority).
If you hit Tootsies at night – the $20 upstairs VIP is a worthwhile investment since the better talent is often found up there – and be careful when negotiating b/c many Tootsies dancers will initially quote sky-high prices (read the reviews) – I’m not much of an extras guy but excluding the room I believe one can get FS for abut $300 for the dancer (some may go for $200 or $250 if biz is slow).
In Broward county; a very popular club is Cheetah Pompano – but I’m not sure about extras there - Diamond Dolls in Pompano has pretty good talent end extras available.
If you hit Tootsies; then Scarlett’s is very close if you have a car; and so is Cheetah Hallandale – both Scarlett’s and Cheetah Hallandale are nice clubs w/ nice looking dancers (Scarlett’s in particular); but I don’t’ think extras are available at least ITC – just mentioning in case you wanna hit different clubs.
