You know, there are endless delays... I'm rather busy these days, and I'm not really in a rush to push things along, seeing as how others are having plenty of parallel RPs I wouldn't want to rush to an end. If you sail now, you could quite possibly make it on time.
Also, I'm pretty sure that all of SA and all of the 'moot was invited. You may simply not have noted it. The coronation was meant to be two days prior to the wedding, but both ceremonies are being merged and have yet to really take place.
