We are to the point that many of us were concerned about. You have little choice but to go with the rubber band. Depending on when you are going, if it is crowded the most coveted attractions run out of paper FPs quickly, a few weeks ago within 15 minutes. So we are where we are wearing MBs if you like it or not. My DS did it 2 weeks ago and aside from not being able to book FP+ for Toy they only had one mega glitch, his girlfriend never, ever was able to enter the park with her band. Every day and every hop she had to go to the iPad tablet CM to verify who she was, her resort and that she had passes. After the first few times they just accepted the group had to wait until she was admitted into the park.
Also, they did not link credit card to band, waiting for the glitches to be worked out before risking that.
