I can tell you our experience via my notes from our trip over Presidents Day weekend which was busy. We did MK on Friday 2/12 and Sunday 2/14 and went different directions. We thought the line for 7D looked too long the first day and moved on, then regretted it. The line stayed even longer all day. This is what we did and how it went.
2/12 (from Yacht Club)
At Bus stop to MK 7:34, bus arrives 7:49
Arrived 8:08, in park 8:13 (already open)
Bailed on 7D, to BTMRR, waited, line started moving 8:34, off ride 8:47
Splash line not moving yet 8:49
Pirates arrived 8:54, no wait
JC small wait
HM no wait - off at 10:00
2/14 (from AKL)
Bus came 7:29. Arrived MK 7:52, passed cars lined up at gate, tollbooths not open yet
7:59 contemporary walkway was lined up at health screen, not open, opened 8:04
Bus health screen opened 8:06
Taps opened 8:11
8:30 off 7D
Off SM 8:48
Off BTMRR 9:15
Off pirates 9:35
I plan to go with the 2/14 plan on spring break as it got us through 3 of the mountains with very little wait. After 10 or so everything had long lines. We did the jump in line just before closing thing for 7D as well both nights which was well worth it, it’s a more awesome ride at night.
We are struggling with ADRs also and looking at some of the same ones as you. I would caution you that LTT and CRT in one day is a LOT of food; if you are doing both in one day try to space them out as much as you can.
