Hi Lou
I'm afraid I don't have coach times. These will be confirmed quite close to departure and you will be sent these around two weeks before you travel.
As for travelling time, google maps estimates around 3 hours for Northampton to Dover but bear in mind you will be in a coach and there may be a stop on the way. Calais to Bruges is about 1 hr 30 mins. So including the Channel crossing as well, I'd estimate about 8 hours altogether - but this will be confirmed when you hear about the pick-up time.
Kind regards,
Olly, your editor
