Hi, we are going on this cruise next year and according to dcl, the earliest departure flight we should book out of London is at 1:15. We disembark in Dover. I'm wondering if anyone has flown out earlier. There is a 12:30 flight that would save us over $1000, so I'm wondering if the 45 minute difference is worth taking a chance. Does anyone know how long it takes to get to Heathrow from the port? Thanks
