The 25 from the bottom of Trafalgar Street is a good way to go if you're in the station area and it's proper busy except it stops all the way up Lewes Road. There are SO MANY bus tops on that road. INFURIATING.
We had one look at that queue at about quarter to 7 and walked down Trafalgar Street and jumped on the 25 at about quarter past (quick jaegerbomb in the Prince George). Made it just in time for KO. Not great really but that's down to lack of carriages I suppose.
