I'll be attending the "Future of Web Apps" conference in London later this week.
The list of speakers is pretty impressive and I'm sure I'll get a superboost out of it.

I learned only recently for sure that I could go so I had to book travel and accommodations fairly late.

The last minute Eurostar train fares are really ridiculous: I refuse to pay 150+ euros for a single 2 hour train trip.
There was a not-too-expensive flight from Antwerp to London early Thursday morning which was perfect, but a flight back late Friday night is non existent.
Damn you airport neighbours that have put a stop to nightflights ! (just kidding - they deserve to sleep like anyone else ...)

After some digging I settled for a weird return trip: I'll take the ferry Friday night to Hoek van Holland - a 7 hour bed-and-breakfast boat trip, and hop on the train from there. (Man, those ferries are cheap !)
Off course they are slow too and it's a big D-tour, but spending Friday night on a ferry boat should be fun as well ;-)

Looking forward to it: traveling always gives me a sense I'm doing some meaningful with my life, like pursuing new insights or explore a mysterious terra incognita.
One thing I know: I'm traveling ultra-lightweight and there will be wifi at the venue and in the hotel. (and for the rest, i'll bring enough movies and tv-shows to last 3 days)

What more does one needs ? (Ah: spare batteries off course)
