A brief summary, as a placeholder to remind me what to write up, flying back with BA before booze in Londinium and a late train home:
Budapest involved a walking tour, the basilica, ruin bars, eccentric Australians, the baths, Terror House, the bunker hospital, food market, getting fleeced by a taxi driver, the parliament, the spring festival and being propositioned by a prostitute.
Our train trip was kept entertaining by spilled beer and busted immigrants.
In Vienna we saw Shonburg, Haptwasserhaus, Freud's house, the Belvedere and ate many cakes.
Not bad for 5 days given the quantities of booze and catching up we managed to fit in as well!
Thanks again for the suggestions folks, it's been a great few days.
