Go for it mate!
I got married in Phil last year without any of my family or friends there. It may make you feel less nervous as I felt better than I thought.
Try to get a good photographer that will video the ceremony as well as the pre-nuptiual thingy.
That way when you return home your friends and family can see in live motion how you acted. Thats what we did and they loved it.
Good luck and have a great time
