As a long time user of acrylic nails I can tell you firsthand they are not comfortable. They feel stiff and it *really* hurts if you catch them on anything.
Due to this reason alone, to the fact that it's important to be comfortable on your wedding day, I suggest having a gel manicure done up to three days before. Gel nails are more flexible, comfortable, less prone to break, and the 'soak off' options are less likely to damage your natural nails. While it's a little more expensive at the salon, I think it's more than worth it.
