For someone who's lucky to have been in a travelling position for the past 15 years and spends about a quarter of my year overseas I understand the benefits of travelling. If done correctly, if gives you the unique insight and understanding of other cultures which you just can't get from being in the UK or at home.
It's also important to consider who may be reviewing your application. If they're from the generation that didn't have the opportunity to 'travel after study' then they may be, unfortunately, tainted by the general stereotypes of 'GAP YEAR TRAVEL' which is hippies trying to find themselves.
If you word it correctly and, importantly, the employer half decent they'll recognise the benefit!
A final point, never forget if you are lucky enough to get an interview, it's as much of an opportunity for YOU to see if you want to work for them as much as them seeing if they want you!
Good luck!
