Just to expand on what has been said, you'll get holiday, but it will be on prescribed dates depending on what course you are on and what discipline you are streamed into. However no matter what discipline you do, the leave will be subject to cancellation at short notice, particularly if recourses are needed, so don't book anything (as I found out the hard way having to forego a trip to the Costa due to a medical recourse).
So you can go on holiday, it'll just have to be a last minute type thing.
