Congratulations on your wedding! 
On WW you can have anything, but you have to factor it into your overall diet. You get a set number of points a day, plus some floating 'weekly' points that you can have whenever you like. There are 3 different plans, each of which have their own list of zero point foods which you can eat as much as you like of, within reason.
I am on purple, which means that for me, most fruit, veg, fish, eggs, chicken, wholegrain pasta/rice are zero points. Everything else costs points. I have lost 4 stone this year, and have gone from a bmi of over 31, to under 23.
What I found works for me is to have very low point meals, meaning I can use my points on snacks that I like and enjoy. So things like stir fries with wholegrain rice, casseroles with jacket potatoes, tasty homemade soups - these things can be 0-2 points for the whole meal. Meaning that I can snack happily throughout the day, or whenever I am hungry. I also batch cook zero point soups and freeze them. If I am ever hungry during the day, I just grab one of these as a snack. Sometimes with a piece of bread/toast :)
I do eat both bread and cereal, but nothing like as much as I used to. The thing with cereal is that both the cereal and the milk are points. I get 16 points a day, plus the weeklies. A small bowl of bran flakes is 3 points. The milk will be another 2-3 points, so thats 5-6 points, just for a small bowl of cereal. That's fine, but doesn't fill me up. I am far fuller eating a bowl of natural yogurt with fruit, followed by an omlette, for instance, for zero points. If I'm particularly hungry I can have a slice of toast and butter with the omlette and it's still only a 2-3 point breakfast that keeps me going for ages.
WW bread is ok. Not fantastic. Unfortunately, but unsurprisingly, the nicer breads (thick, wholemeal, seeded etc) are far more points than the basic low sugar breads. As I love nice bread and cheese, I would rather not waste my points on less tasty versions, but instead I enjoy small amounts of 'nice' bread/cheese as a treat. I have been that person scanning all the bread in Tesco's to find which of the nicer breads have the fewest points per slice (answer: all of the nice wholegrain seeded breads are at least 3 points per slice 
).
Phew that was longer than I intended! Good luck with whatever method you choose.
