The most important reason for going to Uni is study, so choose the solution that will ensure the best results for you. That being said, the social side and networking are important as well for life after uni. You may well fall into a flat of party goers but as long as they are respectful of your space that shouldn't be a problem, you are free to join in or not. My 3 children have always had one or two more timid members in their flats who provided a calming influence, and they all got on well,( admittedly it took a few extra weeks to get to know the more shy elements) moving into private accomodation together afterwards. Different degrees require different study loads so not everyone will be out drinking and dancing every night, and depending on the uni you can select drinking or non drinking flats, single sex etc. Research what is available before deciding to live in or out of halls.
