I'm based in London and have just got my PADI Openwater Diver Cert. I'm keen for me and a buddy to go on a diving break - but don't know the best way to go about it. Are there any London clubs that organise such trips (either in or outside the UK) or any holiday companies that specialise in diving jaunts? Or is it better to get a standard hoilday to a scuba resort (i.e. Sharm El Sheikh) and organise the dive trip when I'm there?
