Great review! We were there the same week because my H was there for the same conference.
I agree with pretty much everything you said, too! I originally wasn't even going to go on the trip with him because I hate the heat and humidity in FL so much during the summer months, but I decided to join him at the last minute. That made me remember why in 2000, on our last WDW in August trip, I said "We're never doing WDW in the summertime again!"
H and I just don't tolerate that kind of weather well, unfortunately...so most of our 20+ trips have been in the fall or winter.
Did you and/or your family actually attend the event at Universal? We opted to go to WDW instead because I get motion sickness on a lot of Universal rides, and we have WDW APs, so the price of admission was already covered.
One last thing...we opted to stay at one of the "included" hotels (AKA, one that H's company would pay for) for this trip, so it was our first time ever staying offsite. We were at the Doubletree near Disney Springs. The hotel was perfectly nice, but I reaaalllllyyy missed staying onsite and not having to deal with driving everywhere! I know it doesn't bother some people, but for us it really takes away from the enjoyment of the trip, so in a way it was nice to stay offsite once just to validate the 24 years and plenty of extra $$$ we've spent over the years to stay onsite.
