FOUND Brian, Justin and the gang going abroad for someone's wedding

[shinya-diey.livejournal.com]

I have problems with finding a story where Brian, Justin and the gang going abroad, Germany I think, for someone's wedding. What I do remember is:
- Justin went a little bit later than the gang because he was finishing some work or did not want Brian to pay for his ticket,
- someone, Michael or Emmett, was sending Justin sms' with updates on what everyone were doing during the trip,
- Justin met someone's cousins who were going to the wedding as well and not far from their destination they got lost because of problems with GPS,
- reception and lodging for the night were in a castle.
Please, help.
