Early morning set up. Got to park at 2 am for a 1pm party. But wanted the best picnic spot and got it. Other families arrived at 4:30 and 4:45!!! Balloons had a marble in each to keep them in the correct positions. White balloons also had some confetti. This looked excellent. And as some popped during the day confetti blew around the party. Was verrrry pretty We were careful to collect all marbles.
