First of all, congrats to you for being asked to be in the wedding. I'm a WW, and I'd say just do WW the same way you would if you weren't in the wedding. I mean, don't try to lose faster than you should. I noticed you used the word Safely, so it sounds to me that you have a pretty good head on your shoulders.
One way to make snacking on veggies not so boring is to use salsa as a dip. If you add 1 T FF Ranch dressing to 1/4 cup salsa, it's only 1 point, and you'll feel as though you had a treat.
Keep focused on the big picture, and you'll do fine.
