Deposit paid for October BBL

I paid a small deposit for a Brazilian Butt Lift in October and now my brain is doing the usual thing where every detail feels huge. The coordinator is answering on WhatsApp, but sometimes it is fast and sometimes after a day, which makes me nervous even though I know they are busy. My main worries are not the surgery itself right now, more the practical side: who meets me at airport, how close the hotel is, and what happens if I feel too sore to fly on the date they suggested. I will travel with my sister, so at least I am not alone. Did anyone ask for all transfers and hotel details in writing before paying the rest? I feel annoying asking again.
