Hi, I am now based at Gloucs so used to it, but it can seem a lot the first time there if you don't have a reasonable amount of experience, particularly where to go in the overhead join. I would suggest working out the day before/on the day which runway is likely to be in use, then work out the overhead join and the taxi route.
Depending upon which day/time of day it can also be busy on the radio, so suggest be well prepared for this also.
The ATIS is receivable some way out so this gives you some time before arriving to confirm the runway in use (and QFE/QNH etc.) / re-work your overhead join if you have to.
