We got a backpack when we bought at the end of 2019, but canceled the
DVC membership within the "changed my mind" period because on basically the day-of, we were sent home from work due to COVID and things were looking pretty uncertain. Disney didn't want the backpack back though. When we signed up again December 2021, we got another backpack about two weeks after our official "close" date.
What was odd, I think, was that the backpacks have different looks, I kind of expected DVC to never change them. Also I feel like we got more "Freebies" inside the backpack the second time than the first. We got the drawstring backpack like three days after we signed and I thought they were already cheaping out and that was all we were going to get, but it turned out the drawstring one was just a "thank you" from our Guide for talking with them and getting information and that.
I don't put a ton of financial value on the backpacks, but they are pretty decent backpacks, and sized that I feel like we can keep them in our owners locker and have as a spare or for the oldest kid to use to carry their own water bottle and that. It is a small thing to DVCs bottom line that makes you
feel good, I think, in that short period after signing away $30k+ that might diminish some of that buyers remorse that is always possible with these size and type of purchases. DVC doing away with them or sending some pop socket thing I would
immediately get rid of would almost feel insulting. Yes, I know, the backpack isn't an Osprey or anything truly deluxe, but I put at least a $30 personal valuation on a decent backpack like that, I put about a 5 cent valuation on some stupid phone accessory.
The only thing I would take in place of the backpacks and find to be very valuable and cool would be if they sent a pair of DVC specific MagicBands. Make them a nice but not outrageous design and put your home resort name on it or whatever, and I doubt those would cost DVC much more than the backpack does, and most DVC members would use it I imagine, at least on their Welcome Home stay.
