how long does the coach stick around for? i presume it takes you to the WP, but would it hang around long enough for the ceremony and photos to be over so it can take you to the GF?
We had the Landau coach, that was my one luxury item and I'm so glad we decided to get it.
It takes you from the GF to the WP and then after the ceremony you would probably want to get pictures taken with it and finally it will take you back to the GF (if that's where your going).
