I’ve spent a good few days doing day trips as opposed to staying a city. Pompeii was my base mainly because the hostel was €15/night rather than €30+ in Naples. It took six hours to get down to Pompeii.
I realised that the hostel has quite particular opening times when I spent half hour pressing the doorbell. Whilst I was at the hostel I had to bugger off at 10am and a not allowed to be back until 2, the problem being that I’m barely out of bed by 10.
