I have used a couple of local Lake Geneva providers in the distant past, but wouldn't recommend them (if they are still in business).  If you are looking for outcall service, I suspect your best bet is a multiple hour date with a quality Milwaukee lady who might drive the 30 - 45 minutes to Grand Geneva Resort.  I'm pretty sure there are ladies who will provide that service.
IF you find a quality provider local to the Lake Geneva area, PLEASE let me know.

I travel to Lake Geneva.

Hi!
I provide incalls and outcalls to both the Milwaukee and Lake Geneva areas.  
Feel free to check out my website regarding details.

Thank you so very much to both of you beautiful ladies.  I really appreciate your replies!
I will definitely be in touch as my schedule becomes clear
