We got tickets during the presale, as we are going to be on island anyway and might as well enjoy the music as long as we have to suffer the crowds. They are expecting to sell about 11,000 tickets, so not a huge concert by US standards. And on a busy cruise day we can get over 15,000 people arriving, so not unheard of crowds, except cruisers mostly stay close to Georgetown. I'm guessing that a lot of people going would either be locals or visitors who would be on island anyway. We know of a few locals who are going. Regarding parking, they will be building parking space for 2000 cars and running non-stop shuttles from other parts of the island to alleviate the parking situation (per the promoter: "Parking passes will be provided to people who purchase a certain VIP-level pass, and most concert attendees will be brought to the grounds through a network of shuttle buses."), and Dart (who built the venue) and the promoters pledged to reduce the inconvenience to the neighbors, but good luck with that
