I have to go through customs and stuff in NAP right? How long would that take at 6:20pm? I am also flying economy. I need to know so I can purchase the correct train ticket. Would I do Customs in LHR or NAP? I am flying from CLT-MCO-MCO -LGW-LGW-NAP. CLT - MCO is on a different ticket then MCO-NAP.. MCO - NAP IS ALL ON ONE TICKET.
