Not a parking question but just related to ISP. Have a one way flight booked out of LGA in a few weeks for me and a few others. The cheapest return ticket for the date we need is with Southwest to ISP. With flight arriving at 11:05pm, it is too late to catch the 11:18 LIRR to Atlantic Avenue I think. So we can either wait till 12:45 (hour and half later) and go to Penn Station and from there to Brooklyn. Or take a cab from Islip airport straight to Brooklyn, how much would a cab go for?
