Has anyone used fake flowers for bridesmaids?

Hi everyone,
We are getting married in April this year & have been told we now have a new menu - this is more expensive. We are going to have to make some subtle changes to accommodate this. Have any of you used fake flowers/ silk flowers for bridesmaids? We have been quite £85 for 3 bunches of Gypsophilia. We are travelling 6 hours to our destination so will be on holiday & have no use for the flowers after the wedding

Any advice would be greatly appreciatedDee
