I went in early Mid March and it worked out really well in DHS and MK, my wife and I went to DHS and got:
ILL for ROTR
G+ for MFSR, MMRR, Star Tours, TSMM
Rope drop for ToT and RNRC, got those done within 25 minutes
Standby for Slinky Dog, TSMM, Star Tours, MFSR, Muppets.
On top of all that I was able to try a bunch of DFB picks that we had been looking forward to (Carrot Cake Cookie, Toaster Tart thing, Ronto Wrap, Wookie Cookie). We were also able to hit Oga's for cocktails, Baseline Taphouse for snacks and drinks, and have dinner at the Brown Derby. Also, I had enough extra time that I was just able to wander around Batuu for like an hour and a half (it was my first time).
