Basically you need to be at the pier for 6.30-6.45, they want everyone on the boat for 7 and it will leave at that time. I can assure you that the boat will leave whether you are on it or not so do not be late!
Dress code: black tie (obviously).
Drink will be pretty expensive on the boat and last year they ran out of a lot of their alcohol so if you fancy a few drinks before then by all means go ahead but if you're absolutely steaming then the lovely people from CPBS probably won't let you on so please do keep that in mind. I would like you all to actually make it on and off the boat.
