Travel Doctor The

These guys are good at what they do - giving the right vaccinations for the right places. They do, however, charge through the nose faster than a Spanish bull in a bullfight for the privelege.
They do claim to provide all sorts of other information about travel health which I guess if you've never travelled before might be useful but for a far less expensive price I'm just as happy to surf the web and go to my local GP.
Long and short of it - if you've got the money and want comfort then this is a good option, otherwise save your money for Pina Coladas when you get caught in the rain.
