......is to get verified by the agency. I suggest using an outside service like Date Check. Then go for the ladies that are in town when you're ready to book. It's best to do everything at the time you are ready to take the plunge.  Ladies can be on "vacation" forever and the agencies either don't know or won't say when they will be back.

Really depends on the agency.  For some agencies that primarily handle DC girls, vacation could mean they're gone for a week to ten days (maybe touring in another location before coming back to their home base).  TGND was like that, with the exception of the German girl who would come back each summer.

For other agencies, like another poster said, "vacation"at a minimum means "this girl toured here before.  She might come back.  She might  not."

My advice is don't focus on a girl that's not here.  Get yourself screened so that when you do see a girl that's available, you actually can see her.  Otherwise, you'll find yourself hesitating on whether to screen now, or not, whether to call now or not.  And guess what, next thing you know THAT girl is on vacation too!

Good luck to you!
