I've been the odd time when there weren't a ton of girls available, depends on time of day though. If you go at a busy time without an appointment there's always a risk that there might not be much selection. Never been "pressured" to go with anyone though, so have similar questions as others about what that really means.
I haven't noticed any significant changes with the new management, other than much softer / comfier sheets on the tables.
Unfortunately they don't have a screen with photos of who's available, they do the cattle call there, always after they take you to the room. I did have an experience once where there was only 1 girl available and I didn't want her, so talked with the receptionist and agreed to leave and come back in 20 minutes when another girl would be available. Wasn't pressured into anything, although granted that was with the previous management.
