If you are planning a 5,000 person "Platinum Wedding" with a month on the French Riveria for honeymoon, then you are going to have a difficult time doing this. If you don't mind scheduling your honeymoon over one of your week-long breaks and you have a good wedding planner, you can still do the "Platinum Wedding".
Seriously, get a good wedding planner; be ready to tell that person what you want and what your budget is (be realistic) and be ready to make decisions when asked, you should be able to do the wedding. A word of advice though, keep your parents out of this. I know that they may be providing the money but they can worry you to death and third year has its own worries. Good luck!
