We are going to stay in positano and will do a day trip to Capri. A friend recommended bagni Tiberio and another one recommended la fontelina. Ideally we would love to get to Capri early and walk around, do some shopping. Then lunch at one of the restaurants and chill out / swim at the beach club. Are there any other restaurant/ beach club worth booking? There will be 9 of us, ferry or private boat? Thanks in advance!
