OK, here's as much as I could get from the footage! Tried to account individually for each team. Note that the journey from Alameda is 20min longer than from Pajaritos.
12.15pm from Pajaritos
Dana/Adrian, Jeff/Jordan, Brent/Caite, Monique/Shawne
(Allie is standing next to the 12.15pm bus when Brent/Caite get on, not sure why they missed it?)
12.20pm from Pajaritos
Steve/Allie, Carol/Brandy
(Dan/Jordan not shown at Pajaritos, but arrive in Valparaiso together with Carol/Brandy)
(Joe/Heidi not shown at Pajaritos, but at Valparaiso are shown between Steve/Allie and Carol/Brandy)
From Pajaritos, first bus after 12.20pm
Michael/Louie
From Alameda
Jody/Shannon
Unknown
Jet/Cord, arrive in Valparaiso right after Jody/Shannon
(They say "I see the green team, they're ahead of us," which suggests they took a different bus?)
