Mixing practice

I've recently started DJing at an event in London that takes places once a month. My selection of records is, of course, stunningly good, but at the moment, as a novice amateur, all I do is play tracks back-to-back, i.e. little or no mixing, just ensuring that there are no silences. Does anyone know if it's possible to practise DJing technique anywhere, like, say, a studio one can hire out for an hour or whatever?
