I was thinking: "Taking The Plunge Best Wishes"
Anyone Els have a better saying they could add? they want foot prints in the sand and wedding will be on the beach.. So the bridal shower cake is a beach them just don't know what to write on the cake?

How about something like:

1. Like our foot prints in the sand, I will walk through life with you.

2. Lets ride the waves of life forever.

3. Or: We will ride the waves of marrige together, forever.

4. The sounds we hear in a seashell, is the sound of love in our hearts.

Hope these can help you out.

God Bless,
Sharon

I know you posted this 10 days ago, and not sure if you still need any ideas, but below are a few off the top of my head:

1) Just like the sand and sea, you are where I want to be.

2) Of all the fish in the sea, I found the only one for me!

3) Life's a beach! Watch out for crabs.

Okay - so that last one probably isn't much help - but I think it's funny!
