We made the decision to claim our baggage instead of using the ME tags that we received. When we were waiting to grab our bag from the carousel, we saw DOZENS of bags with bright colored ME tags (and no owners to claim them). They circled the carousel the entire time we were there and I did not see a Disney ME CM looking to claim them. This occured on a Delta Song flight from Hartford on Saturday 5/14 at 6pm. I saw it with my own eyes, and my DH and I were horrified for the people who thought they'd safely checked their luggage with ME.
As a side note...we claimed our bag because we were unsure of the delivery timing to our room, not because we had any idea that bags circulated the carousel. Now that we saw bags circulating (maybe it was a one time occurance), we'll probably claim our own bag again if we do ME.
