Good luck matey - I'm sure you've got nothing to worry about after 10yrs.
I'm in a similar predicament (8yrs), but not sure about another country. I'm absolutely fine with it, but she might want something in this country with family and friends. (personally, i'd like to keep it low key - after all, we're pretty much married anyway!)
Is it just you two, or are you taking any close family out for the cermony?
Maybe a bash when you get back?
