The sand ceremony was done within our actual ceremony. Like right after we put on our rings, we then did the sand ceremony. Then we went back to standing in front of the arch & thats when the officiant did the "i pronounce you man & wife" part. So if you really want to do that, it can be done within the ceremony.
As for walking down the aisle, yes, we walked down, got a few feet away, had our little hug & kiss & then turned around & came back to our guests.
At some point after the ceremony our guests were given rum punch & champagne. I don't know when this happened because I think we were with our photographer. But there was no toast really until we had dinner at our reception.
If you know that your guests don't drink & won't really need the champagne then skip it. Or maybe you could have something else other than champagne like sparkling cider. Maybe thats an option & it will satisfy your mother's wishes! LOL.
I don't know how this will sound, but if your guests are going to be offered red stripes & water on the busride back to the restaurant, maybe you can do a "red stripe" toast on the bus, ofcourse before the driver takes off. I'm thinking that would make for a cool picture-everyone on the bus holding red stripes in the air & toasting to you! Sorry for sounding corny!
