Oooh.. sounds like you had a lot of fun Koga. I have always wanted to take the ferry to Amsterdam because it leaves from where I live, is quite cheap.. and because it sounds like a lot of fun. The only problem is that I have never found someone I could go with. My ex was gonna come with me once but it ended up with him inviting all his friends too and they just wanted to get stoned.
I start a new job soon though and have also enrolled on an evening course so there are loads of opportunities to meet new people... one of them will surely come with me to hold back my hair while I am leaning over the side of the ship emptying my stomach. hehe.
I do hope there'll be weird coloured drinks too.. or at least weird coloured drunks..
