We did this a couple of years ago & it was great. A CM took photos for us whilst another server conducted the "ceremony" with Pluto in attendance. You get a souvenir certificate to take home. I did get rather embarrase when asked to snog for a count of 100 - luckily the count goes up in 10s!!! It was a little bit magical & a bit different without costing us anymore than the largest icecreams I have ever seen. DH even gave me an eternity ring at the end of the ceremony.
