You can do online checkin as soon as you link your resort reservation to your
MDE account, and online room location requests can be made as part of online checkin. However, the choices online are limited and might not suit what you really want. If they don’t, it’s best to leave that section of online checkin blank and submit requests to
DVC MS directly. DVC owners can do that via chat, email or calling MS; renters need to ask the owner to do it for them. Guests paying cash to Disney need to call the resort reservations number and submit requests that way.
