Yes. 10,000 participants. 15,000 is including staff. Jamboree really sucked pretty badly compared to past Jamborees.
Examples: no “headline” guests (literal promise that Jack Black was going to be there as part of a team building activity was a literal joke), no arena shows (no gathering of everyone at the jamboree, none), only the smaller climbing area was open at the summit, the canopy tour wasn’t open, and not all zip lines were open. My daughters were like “meh, what can I do here that I can’t do at camp?” They CAN Wait Until I Go Back. Not interested in future Jamborees.
