I did the parade lap last year. It's kind of difficult to stay together because you get separated when you moving into the holding area before hitting the track. Unless, of course you'll all try hard to stay together but there's like thousands of people going at once into this holding area and people that direct you, that's where you might get separated. But meeting up before going into the Laguna would be best bet, so at least you all go in together. That was my experience last year.
