So, when a member of the family says, "You must stay at the Biltmore when you come to Miami!", and arranges a family rate for you, I suggest you take their advice.
I'm typing this from an executive suite in the aforementioned hotel and it's lovely. Switching to dorms for a couple of nights during YAPC is going to be something of a comedown let me tell you.
Oh yes, the journey was horrible. Last time I believe the BA website and troll off to terminal 4 to be told that the Miami flight is the only BA flight to leave from Terminal 3. And it's a bloody good job I brought the 'useless' tickets along (we'd booked on e-tickets, so the bits of paper that showed up the day before we left home seemed somewhat extraneous...).
