Trains from Folkestone don't come into Victoria.

Catch the train from Folkestone to Charing Cross. Walk to Trafalgar Square
and take the no 9 bus from Stop S all the way to the Royal Albert Hall.

I believe that Stop S is to the north-east of the square - the opposite
corner from Charing Cross, but look at the map on any of the bus stops
outside Charing Cross Station to find its exact location.

The No.9 is indeed likely to be the quickest route, but get it from Stop
H immediately outside Charing Cross Station - Stop S is in Cockspur
Street and not the best choice. The spider-map will show the OP the
whole route, and the boarding and alighting points:
