I had mine at Fenchurch. I stayed in a hotel just 5 mins away, the ibis London City. I wouldn’t recommend a long ride home, I was quite ill after and could hardly function for 2 days after. I was told my admission time 2 days before but they changed it the night before. My op was on the Friday and yes they do it at Fenchurch, then my follow up was on the Monday, but originally booked in for the Tuesday, then got in for the Monday. I went to Bristol fir this cos it’s closer to me.
I stayed the night before and the 2 nights after, I originally booked just 2 nights but needed 3! Then I got the train home.
