I strongly suggest that you study all the threads in the last month or two that discuss this topic, just so that you can see all your options when the ferries are very crowded.
The time that you are going is one of the most crowded times of the year, just like it would be at DisneyWorld or any other warm weather destination. So everything you read in threads about July will apply to Christmas/New Year's week.
It's impossible to say whether you would be able to find tickets on the 27th in order to travel on the 28th. But I'll say this... I sure wouldn't count on it.
And 9am ferries are always the most popular. You will probably find a seat eventually, either later that day or even the next day.
If you know a local, have them buy your tickets in advance.
