This is it.  This is the week that will serve as a barometer as we go into Spring Break season. 
As of right now, on Monday 3/14 at 10:40 am, all of the rides listed in the OP are out of G+ LL reservations.  HS opened at 8:30 am with a 8:00 early entry.  Yikes.  I can't wait to hear back from folks that are there right now as to how G+ worked for them, particularly at HS.  Since this post was originally written, I have been following HS crowds pretty closely and, over the past few weeks, really started to come around to the possibility of trying a tap-and-go method at HS in April.  But today shows me that is not a possibility.  Today, if we had rope dropped HS, my family of five likely would have gotten one G+ at 7am and MAYBE another around 10 am if we were lucky enough to snag a G+ with an early return time.  And that's it!!!  We are screwed.
(I will say that I refreshed just before finishing up my post here and, at 10:47 am, a few rides do show up with later return times: MMRR (8:15), RNR (4:50), TOT (8:20) - but who knows if there are 5 for my family.)
