As far as I know they will be shipped or handed to you. Might as well customize them. With the two I got in October (customized one then thought I left it at home so I got a grey one at the resort) and the 4 coming up for our January trip with 4 separate reservations, I'll have all colors but yellow. And I like it that way.DH and DS aren't as thrilled as I am, but they're trying to have some fun with it.
Except for when you're actually at the resort, where is the opt out spot? I think so, too. Even with the shipping, you just KNOW that they have some sort of AMAZING deal with UPS right now. Companies have amazing pull with shipping companies; the prices they charge us are certainly not the prices they are being charged!
I will have 5 in October!! What you do now is start to decorate them yourself. Right now, I have a sparkly pink one with rhinestones and a Christmas one with sparkly red. Am planning a Minnie band in May. Then a Halloween band in Oct, followed by a black sparkly one with silver bling!
