I can't wear the Neutrogena helioplex on my face - I get a weird reaction and my face, particularly around my nose and mouth, swells and dries - and then for about a week my lips are chapped and peeling. So try that one before you commit to it two days before your wedding. And I say that as someone with no known allergies, it's the only thing I've EVER reacted to.
Personally, body-wise, I use the sprays - coppertone sport SPF 50 is my preference. They go on dry and stay that way - just be sure to rub it in a bit after you spray it on.
For my face, I use blue iguana. It is a bit greasy, but my recommendation is to have loose powder and a good powder brush at hand - that way if you get shiny you can just powder up. Also, some of the new loose powders have an SPF in them.
