They do have kiosks in STL but, there is not a problem if you swipe multiple cards as, even if it is manned, they don't pay much attention unless you ask the person a question. May not be worth the trip if you are traveling though as it is only one point.
Sounds like Tahoe is really the only properties where there might be some issue with swiping multiple cards. I do believe you have to swipe before play to "activate" the game. At least that is how their other promotions usually work.
