Hi there,
We had the same problem - getting married in a different district from the one you live in. It is standard procedure that you are not allowed to book in over 1 year in advance. We did not find this to be a problem at all - we just called up the registrar one year in advance, first thing in the morning, and booked the date and time we wanted. As everyone is in the same position - its not as though you are being treated unfairly. Giving notice in your own area is not such a big deal - just call them up once you have a date and time booked and set up a meeting. They only need two weeks after you have given notice for your papers to be ready - and the registrar marrying you doesn't need those papers until your final meeting - 6 weeks prior to the actual marriage.
Don't stress - you really have loads of time.
