When we were at MGM in June, I waited for 15-20 minutes in a line up at the top of Fantasmic, to get supper for my very hungry family to eat while we waited for Fantasmic. Having had an "issue" two years before over the inability of some carts at MGM to take my room charge, and having discussed it with a CM who told me that soon all carts with electricity (read: electric cash registers) would be able to take room charges (and presumably other credit cards), I observed while waiting in said line for 15-20 minutes, that these stands did "indeed" have electric cash registers. When it was my turn, I ordered and then produced my room charge. I was told, "We cannot accept room charges." At that point all I did was ask the CM, "If I go back to my seat and get cash from my husband (sorry, I didn't have the $25-30 that 4 hotdogs, and sodas were going to cost<g>), may I come back up to your register and not have to wait again in such a long line?" The CM said, "No." At that point I asked to speak to a manager. To tell the whole story, there "is" a small sign (maybe 2x4 inches) stating "no credit cards" on the front on the cash registers, but they are certainly not noticeable from the back of a long line, and when you get close you have to be looking right at it to notice it. There is certainly no sign hanging from the top of the stands where the menus are listed which says "no credit cards", or at least there weren't when we were there in June- the manager I spoke to told me that he would make sure that something was done about it. He "did" let me go to my seat and get my cash, and then go to the head of the line, but by that time I had already waited quite a while. What he explained was, yes the cash registers are electric, but they are unable to run the cable necessary to authorize credit transactions, under the concrete on which these stands sit.
So, this is one place where you might think credit cards are taken, but they are not.
