Most couples watch movies whereby it is known to have a rehearsal dinner the evening before the wedding. This is completely up to you as the couple… but remember these are unnecessary expenses. Most traditions offer this and if this is a tradition you would like to fulfill then you have a good to excuse to have an extra party … and everyone loves an excuse to party. But this is not a need so can be avoided.
It would be ideal to have a rehearsal walk down the aisle practice so that everyone knows what their duties are and how the routine will go for the day of the ceremony. This too does not have to take place the night before as most brides are in such a state that they need the night before to relax and finalize last minute arrangements. This can, however, be arranged a day or two before the wedding.
An additional con about having a rehearsal dinner is that the couple tend to have a few glasses of champagne which cause them to be tired the next day and you also need to avoid indulging in a large meal to avoid any discomfort.
This is a tradition that can be seen as special and not so special, but none one that you as a couple need to abide by.
