We studied the wait times for the attractions at each park and decided to stack. We had some learning curves on day 1, but by our HS day we had it down. Started at 7 am and grabbed 2 SDD and 4 ToT (granddaughters wanted to do SDD). Staying offsite, had to wait until 8:30 and grabbed an evening $LL for RotR. Next, we went for MMRR, then MFSR, then TSMM. We had pool time until time to get ready to go around 12:00. We actually got to the park at 1:00 PM and watched Indiana Jones at 1:15, then Beauty/Beast at 2:00. Our G+ for ToT was 2:40, so we went over to the Cars show, then ToT. (RnRC was broken down most of the day so we didn't even try for that). By the time we got off ToT it was time for MMRR, then time for SDD - except it was down, so we watched the Mickey and Minnie shorts, then went to S Tours. Finished there, time for Mama Melrose. After dinner, time for RotR except it was down - so we walked over and did Muppets, then MFSR. (after SDD went down we dropped the TSMM and grabbed a later time, so we weren't running all over the park). Finished MFSR, and RotR was back up, so we hopped on that. Time for TSMM, except DGD left her ipod on Rise, so parents went back - successful find. Hopped on TSMM and got off in time to do 1 more attraction before the park closed. Almost no line for SDD but we had done it 2 days prior so the Grands decided to do MMRR again, and the park closed. Except we had after-hours reservations for Ogas, so we were able to walk through a practically empty park and unwind at Ogas. Great day. Opted not to do: RnRC (down too much), AS2 (too rough), SDD (had done it previously), and Frozen Sing along (girls just weren't interested last time we saw it). Oh, yes, we also walked into One Man's Dream while walking back to ST earlier in the day.
If I had it to do all over again, I would drop the Mama Melrose dinner. Not that there was anything else we'd rather do, it just wasn't worth losing park time. There was something else we could have done again, like MFSR. (We will let the girls do SDD together, but we think they're too young to use Single Rider).
ETA: As for grabbing an attraction, then going for another G+ after you tap, we found the earlier available rides weren't a long wait anyway. We decided to go for saving time vs quantity. We are a family that doesn't like to plan, though we have to these days, but loosely if at all possible. We also are a peculiarity in that we don't think a 20 minute or less wait time is a big deal. We would rather use the G+ to get the attractions with the super long wait times. Refresh is also your friend. The only attraction I wasn't able to make magically appear through refresh was Jungle Cruise. Of course, there were some we already had so we didn't try for them. This is just our touring style, though. Others find different touring styles work best for them.
We only bought G+ for MK and DHS. We also don't hop any more.
