You can also choose to have different wording on each side of each bus. In addition, wording can be changed in the middle of the event during down time.

Pre-Ceremony: Jack & Jill Are Getting Married!
Post-Ceremony: Jack & Jill Just Got Married!
We have the following symbols: #, @, *, &, (heart shapes) ♥, ~, !
