DH & I are local AP's and go to WDW every 2-3 months so we are building up quite the MB collection at the moment. I know that you can use any of them interchangeably and we did this on our last visit in March (Ok, I did. DH could care less if he "matches"
). My question is, does it matter which MB you use to initially check-in? I know they just read your MDE account, but for some reason I always feel like I HAVE to use the set that was sent for that particular resort ressie when checking-in. Is this true or false? Also, would any MB (other than the one used to check-in) be able to open the room door? Looking back on our last visit, DH always opened the door and since he never switched MB's to match like his crazy wife I am not sure if that is possible 
Thanks in advance!
