Thank you for your thoughts. I do understand that it is a difficult ADR. I have been checking at least once daily without any actual problems performing the search.
Even when there are no times available, you are able to select a date and time to search. I am unable to select any dates at all (all the way for 6 months - they are all greyed out.), and the time drop down box just says 'no time available'.
Can someone else check if they are experiencing the same issue? Here is a direct link to make it faster for you:
