I spent the weekend in London. My first time flying in to London City Airport, courtesy of City Jet, and I must say that it is the only way to travel there. Its close proximity to the city saves so much travel time.
I stayed in Covent Garden and partyed hard. A weekend of debauchery as it were.
Incidently, people moan about how expensive Dublin is - try London for a weekend of socialising and you'll know all about spending.
