Slinky and Rise are insane. Just back from the World on Sunday and did two days at HS.
Day 1: Went for Rise first, got it no issues. Then tried to get SDD, gone by 7:04. Kept refreshing, at 7:10, more times popped up, and I was able to grab 3:30-4:30.
Day 2: Went for SDD first, got it for 3:15-4:15, completely gone by 7:02.
I'll continue to say this, but Genie is a must for HS. Also paid for Rise and MMRR, which made HS an expensive park day, but we nailed everything we wanted in about 6 hours, made it a very pleasant day.
