When I asked customer service at disney shopping about returning an item to the parks they said that wasn't an option.
I admit I once did a switch like someone suggested up thread though. Luckily the tag from disney shopping was exactly the same as the one from
Disneyland, sku and all, so it wasn't a problem. Of course as Liza pointed out, that may not always be the case.
I didn't see the harm since there was nothing wrong with the bag I returned, I was just exchanging to get a different placement.
I would have chosen #2 as well. I love how the castle is perfectly centered above the D&B tag, and you've got a great Cheshire Cat and Dumbo whether you carry your bag frontwards or backwards.
Maybe you could find a wristlet that has Mickey and a tea cup well positioned? That's probably what I would do.
I hope the missing packing slip is an easy fix. Obviously they have all the info, so it really shouldn't be a problem, but still... yikes!
