So we are on our 5th day of our trip to DW. We still have tomorrow to go. It is busy here, busier than the trips we have done prepandemic. We tried G+ once late afternoon/evening at MK, stacking while we were at HS in the AM. It was helpful to hit a lot of more popular attractions. The rest of the trip, no G+. We hopped on 7dmt during the fireworks and had a 5-10 minute wait. We rope dropped a bunch of headliners, including RotR.
Just my opinion, G+ is not needed if you know what you are doing. Mornings and evenings are the best for wait times.
I understand utilizing it for short trips or if you don’t want to get up early. But G+ is not an absolute must, especially when staying onsite.
