We went the weekend before 4th of July and we heard many locals say it was was "dead". We rode Resistance 3 times with lines under 40 mins, though it varies as we saw it 1.5 hours long at times.
I hated to support it at first, but we got Genie+ all 4 days we went and it was worth it. Especially if you don't go often. Me and my wife went, so it was just $50 a day, but if you have a big family it'll add up.
I loved the Tron and Guardians rides, but I would not do the individual Lightning Lane to ride them as that is ludicrous. Guardians was essentially a walk on for the virtual line, Tron we still waited an hour to get on (half of the line is in a poorly shaded area of the walkway and was brutal to be in July's sun.
TBH we will probably skip AK next time. MK is the classic park, but honestly we only rode Mansion, Tron, and Buzz light-year and made it a half day with an EPCOT visit the 2nd half. EPCOT's center is under construction, so maybe wait until it's finished. It was closed our last visit too. Hollywood studios we park-hopped to it every day for something.
We only did July as it was our honeymoon from our late June wedding, but we are never doing the summer again...it was brutal. 98 most every day and 60% humidity. We'll go back to our November visits from now on.
Oh, not sure if it was just the app as I just downloaded it. Thanks~~[write text here]~~
