We had some issues when booking our accommodation for next year. I can recommend sending an email to the Directors (e.g. Robert Iger Cheif Exec WD, or Justin Kliger, Head of Travel WDTCUK - google for the email details). We had a response within 30 mins and everything was sorted to our satisfaction.
Was a shame it didn't go smoothly to start with as we have a very tense week, but we are very happy now it's sorted.
