Your doctor will be the best judge of whether the surgery can be postponed. In some cases there can be a danger of perforation or blockage of the bile ducts in the liver, which can be very serious indeed. If you decide to postpone the surgery and go ahead with the wedding and honeymoon, you might run the risk of having another attack while away from home - which could be very scary.
Perhaps you could go ahead with the surgery, wedding and honeymoon but get some kind of travel insurance in case you aren't well enough to go on the trip.
I had my gallbladder removed laproscopically about ten years ago (after losing weight quickly on Nutrisystem - another good reason to lose weight slowly!) I was pulling weeds in the garden a week later and felt pretty good two weeks after, but as they say "your mileage may vary".
You will be very bloated immediately after surgery as they fill your abdominal cavity up with air, but this subsides within a couple of days.
I have just a teensy tiny scar on my upper abdomen (less than 1/4") and one in my belly button that isn't visible.
I hope everything works out well for you.
