They did the mini waves last year for Princess too, so I'd guess they will do the same this year.I’ll be running the 5k and the challenge at Princess! This’ll be my 2nd Princess and my 8th runDisney event My best friend who started running last year wanted to do it and this will be her first runDisney experience so we’re super excited! 9k people in corral F sounds nuts! I wonder if they’re planning to do the mini-corral thing like they did in January (it looked like they split up each corral into like 2-3 groups and there was a 2-min wait between each group)? That was really confusing.
