I have been trying to use the Online Check-in service on My Disney Experience for about a month now, but always get hung up on the credit card info. screen. The site keeps "thinking" and never takes me to the next step. . . so frustrating! Anyway, would online check-in help improve my chances for getting my room requests or is its purpose only to save time at check-in? Is anyone else having trouble with online check-in or might it be my computer?
