We had the 6:00 seating on the 7/6 Western and I can't imagine moving that up any earlier - The 8:30 was definitely too late for us, but it was alot of work getting 4 of us showered and dressed in time for 6:00, especially on port days. 7:45 actually sounds like a perfect time, but I think 5:30 is really pushing it. It will be interesting to see what the feedback is.
