Buying tickets in advance is the best way to visit Brighton - there's a tip from me to you. Otherwise, it's an excruciatingly expensive place to get to if you buy tickets on the day! I realised this the day I wanted to go, and promptly booked tickets for the week after!
Unfortunately, the day I picked was not as nice as the one I wanted to go on... But hey, them's the breaks! Despite the chilly weather, wind and clouds, I had a lovely time there. The lanes really are amazing, and I had a very tasty dinner at Terre a Terre. Yum.
