how to get to hotel brittania grand burstin hotel from national express coach st/whitfield
Walk down to the harbour. It's the largest and by a long way the ugliest building in Folkestone
That doesn't really answer Abhik's question as Whitfield is on the outskirts of Dover and about 5 miles from Folkestone.
Abkik - are you taking National Express from London and if so are you not able to get a coach directly to Folkestone? Otherwise the best option is a taxi, as by bus you'll need to travel into Dover and then catch another local bus to Folkestone.
