If a provider's incall location is always some hotel does that mean I have to pay for the room and I have to take into account that price along with her donation?

As far as I know, no you don't.

Or there is a room that they have the girls rotate through, like rotisserie chickens.

Typically indies [independent providers] pick up the tab for the room, but it'd be best to check.  Usually, you'll see language in the ad like 'everything included, nothing extra needed'.

Agencies are a different story.  Best to ask.

Cheers!

....ROFL. Now those could be some "hot" chicks. Michelle you really have a penchant for some "one liners". I couldn't handle the "production line" atmosphere.

BTW did any of those Bruins take advantage of the discount during the NCAA mens basketball tournament and perhaps "prove" that they suck at other things besides basketball? LOL

Sadly Kentucky didn't make it into the Final Four but at least they made it to the dance. Maybe next year, or NOT! Way too unpredictable.

If you go to meet a lady at her location, it is safe to assume that any "cost" to you for the room is already factored into the rate you'll be paying.  You should find out such information beforehand if you have any concerns, either on her website or by direct contact.  There is a possibility that you might be "upcharged" for services, particularly with an agency.  Obviously, try to avoid that scenario if at all possible.  However, that is something separate from the hotel room cost.

If you inquire about meeting a lady, and she indicates that you will need to get and pay for the room, that would make the session an "outcall".  You would then be responsible for the cost of the room (unless you wish to have her meet you at your residence or a friend's place or similar venue where no payment would be necessary to secure the location of the session).
