yo george,
you can call for massage in a service apartment, unless u have people sharing room.
are you in seoul now ?
as for the business club, dun go on friday nite, they will include the waiting time in the 90mins..
for most trips I will just call a massage to my room, sex and dinner in my hotel room ..., other time I will go out with my korean girlfriends, they are very gentle and nice towards foreigner ... and when they speak they like to be close to you ... sometimes they will serve you drinks and food during dinner ... buy them flowers or softtoy and they will be happy ...
not all can ONS, be brave and just ask, and the some motels are better than the 5 stars hotel ...
gee I miss korea ...
