Think you need current advice from Tunbridge Wells not Portugal. The Weatherspoon's Pub - where there was a recent hygiene issue that closed the pub for a number of days - can easily be usurped with far better places to visit.
The Pantiles to Dunorlan covers a number of miles - so both may be an issue; however if you are arriving by train then the High Street and Pantiles are easily accessible. There are a number of fab cafes on the Pantiles - Woods is just one and one of the older ones, with newer ones springing up all the time. Wander around and enjoy the shops as well and visit the new hotel, 1 Warwick Park.
Royal Victoria Shopping Centre whilst having a multitude of shops, offers very little that you won't find anywhere else.
Camden Road is the opposite direction tot he Pantiles so check distances.
