We are looking at a trip that would involve transferring trains at Ashford International. My sister has a walker and we will all have 1 large checked size bag as well as a carry-on size bag. They are giving us 6 minutes to transfer from 1 train to the other, currently assigned from platform 5 to platform 8. With all the luggage and the health issue, is this enough time? We will not be able to sprint anywhere! The other option is to wait an hour for another train, at which point, we may as well take the slower train to Kings Cross via London Bridge, as we'd arrive at the same time.
