its nothing special, just the end of a long row of rental car counters. If you go to level 1 on the B side and go all the way to the right as you face the windows or left as you face the counters, you can't miss it.
There is also Disney castmembers as you proceed down to the lower level that are directing you to the desk with huge Mickey gloves on & it really gets me in the mood & I realize the magic is just beginning !!
