Hi everyone! thanks for all the great answers! I will book the 12h50 flying out LGA and yes, I have travel insurance. Looking at your answers, NCL maybe not the best option. I thought that they would be faster but doesn't seem so as they wait for everyone to be onboard a full bus before going.
@mking8288, I didn't knew about Dial 7 or Cabify for Portugal. I will look at this option. Otherwise, I will take an Cab or an Uber.
Thanks a lot everyone!
