No real problems then - just make sure you have a clean hanky (or similar) to cover your head at relevant points of the ceremony.
You may find that male/female guests are placed at separate tables, but in my experience 'white' females (for want of a better way of putting it) are usually treated as 'honorary males' and seated with their partners.
It will be a long day and almost certainly run well behind any schedule you may have been given. Relax and enjoy - the food will be lovely and the hospitality better.
