for barcelona, exluding the usual pasport, ticket etc..
factor 50 sunblock, for me plus 8 cans of strongbow (to bring my luggage up to the 15kgs limit) have you seen the weather forcast for the weekend?? 26 degrees, add a few for the stadium environment we're talking 30 degrees minimum!

that's me turning red!
what other things are vital for that away trip?
