Every party will now do a full standby every time vs going LL to LL.
For example...
Party A
DAS - 6 people
2 rides with 1 hour stand by waits (and LL waits of 15 min) - Party A makes reservation at gate at 9am
Arrives at ride 1 at 9:10am and enters LL
Rides as a full group and gets off at 9:25am
Makes reservation for next ride at 9:30am (10 minutes after they checked in to the ride) for 10:30am
Gets to 2nd ride at 10:30am and enters LL
Rides by 10:45am and exits
12 Tier 1 rides done
Party A parent swap - 6 people
Enters park at 9am
Arrives at 1st ride at 9:10am
Gets rider swap entry done by 9:15am - party of 4 enters SB line, party of 2 waits
Party of 4 out at 10:15am and now swaps with party of 2
Party of 2 now waits in LL and is out by 10:35am
Party of 6 now walks to 2nd ride and arrives at 10:45am
6 Tier 1 rides done
Rider swap vs DAS will cut lines by 50%...it always takes time vs DAS that takes no time...it is the ultimate way to accommodate while drastically reducing lines and making cheating effectively worthless. Less rides can be ridden, even if you had an extra rider with a group. It's WHY they let an older brother or sis ride twice with the baby swap (once with mom and once with dad) - they have to wait so long to move on from rides each time, so it gives them a bonus.
