yes, the train Gent St. Pieters to Antwerp Central, goes first to Gent Dampoort and then 20 min later in Lokeren all railinfo you can find here, in English btw : http://www.railtime.be/website/home-en/
Double snap! We're booked on the 1200 ferry aswell. Although I'm going to try and change it to 1000 tomorrow. More beer time that way!
The site I checked yesterday said the Brussels trains went to Sint Pieters and the Lokeren trains also went from there, so I booked a hotel opposite Sint Pieters Station.
We were looking at 12noon but decided that's a bit late, it'll be 3pm by the time everyone is off the ferry. So we've gone 10am instead.
I booked 12pm but we've since decided the same thing, so I've just amended the booking to go at 10am! Crossing was £4 cheaper with a £10 admin fee so £6 to change. Works out at £116 all in with fuel, ferry, digs and match ticket. Can't go wrong with that!
