Just Back 7/2-7/9
1st stay at Saratoga Springs and was very impressed. SS is a DVC resort but I do believe you can book there. It is a HUGE resort, spread out over 5 or so sections. 2 of them are considered preferred—and are slightly more expensive—but they put you closer to the main hospitality or a view of Disney Springs right across the lake and DS within walking distance.
Backstory: we didn't plan for this vacation, but my 16 yo daughter got invited on a friend's Sweet 16 trip/gift. MY wife wasn't keen on her being so far away, so we booked to align with their trip "just to be there"....moms

. The girls and their family stayed off site at another timeshare. We also traveled with another one of the guests families, we all are friends through daughter's dance team, so they rented some of our DVC points and we got a 2 bedroom lock off with them.
So its was a little non-tradtional trip: me, wife and my 12 yo and the other family of 3. To save $$ we didn't have hoppers and only did a day in each park and planned a lot of full days/rope drops which is contrast to my normal style of popping into a park in the AM, then going back to resort and resting, and then into a different park at night.
some observations:
1. Right off the bat, I love/hate Genie plus. I was in the "hate" camp since it came out. I used it 1x before for a quick trip but still found it annoying. For this trip, wow, what a difference!
1st the hate: I hated getting up before 7am to make that initial paid lightning lane selection. I don't get up that early for work everyday, let alone on vacation. But since we planned on rope dropping things, it was too far off from when we needed to start getting ready anyway. I don't like paying for the rides, it left a bad taste in my mouth...$90 extra for the 6 of us for 1 ride. We limited it to just 2 rides, Rise and Guardians, but it forced us to def RD the other parks.
Now the good: if you are fairly savvy and know what is worth booking a reservation for or not, G+ is pretty bad butt. I cant say there was anything we missed out on that we wanted to do. My only real complaint is that you cant pick your booking time for the attractions, it a take what we have kind of thing. And for certain attractions, say ones that were across the park or if you wanted to break for lunch, you had to hold off booking these and keep checking to see when a time was right. If you got lax on that, you may find the reservation time jumped too much later and you are screwed.
I know people complained about being on your phone all day, but I didnt feel that way. No more than scrolling FB or twitter. Plus 75% of the day you are on line, so do it then. Unlike the old FP, you can have overlapping reservations, so you need to be careful about that b/c it does reduce your time window to make that 2nd reservation.
2. Guardians of the Galaxy ride was really fun! I'm not going to spoil it but the rotating cars not only help with the storytelling aspect, but really enhanced the overall ride experience. Most of the ride is just a roller coaster in a dark room, similar to RnRC, but the rotating cars made it 10x better.
We did buy the paid LL for it and also got in a boarding group. We did Epcot on July 4th. I expected higher crowds so I wanted to lock in that ride at last. As for boarding groups, this is where these things annoy me. We didn't plan on getting to Epcot until later, knowing we would be there all night for the Fireworks. We went to jump in on the 1st boarding group drop at 7 am but realized we have no control over when we would need to be there, so we decided to wait until the 1pm drop (thankfully there was one)., but again, knowing the crowds were high, not knowing how many people were being admitted into the BG's, was giving up that opportunity going to cost me getting shut out?? Thankfully it didn't, but I got right in at 1 (this is where the #### watching game sucks) got a BG for 6ish pm. Thankfully that didn't interfere with my planned dinning which would have been a whole other issue.
3. Profiles/Traveling party groups are a hassle when it is minor and you are not traveling together. We spent a good chunk of the day working this out with the guest relations team. My daughter was with the other family and we were having issues making reservations for my wife who "controlled" my daughters profile. Same for them ,they kept getting my wife added to their reservations. Unfortunately, when everything is digital, little scenarios like this can really put a dent in your planning.
4. 4th of July fireworks were Epic. We did Epcot on the 4th, mainly b/c it easier to get a good spot anywhere around the lake than waste hours standing shoulder to shoulder on Main st IMO. I will say, Harmonious is growing on me, I still miss Illuminations, but Harmonious is not a bad replacement. THey added about a 8 minute 4th of july tag right after Harmonious and it was insane. You couldn't see the across the lake afterward b/c of all the smoke.
Pro tip: if you are looking for a good spot to watch Harmonious, dont worry about getting up close to the railing, look at pavilions in WS that have open courtyards up front. You dont realize it, but the countries are slightly raised from the main walkway and it provides just enough lift to get you over the hordes squished against the railing. We watched from Japan, maybe 20-25 feet back from the main walkway and it was perfect.
I'll add more as I think of it
