Yopd and dbs

Hello I’m being referred for dbs as struggling to tolerate meds. I’m 44 and been diagnosed 4 yrs I’ve been advised queens specializes more with yopd and dbs but the rvi is closer - can anyone give advice on their experience with either of these hospitals and their dbs journey ? If only a couple of appointments needed I’d be happy to travel to queens but not sure how many trips needed for assessments, procedure and post op care? Any advice ? Tips etc would be greatly appreciated ? Thanks
