I was in Galaxy's Edge earlier this week, while we're on the topic. I feel like I had the perfect Galaxy's Edge experience.
- Entered the land at night, so the lack of shade was not an issue
- Queued up for Rise of the Resistance after 9pm and waited 15 minutes (30 minutes less than the posted wait time)
- Caught the "Fire of the Rising Moons" fireworks show (perfectly pleasant)
- Tried the Rondo-less Garden Wrap (turns out, it's among the best food items in the park)
- Walked past the impressive Falcon (and ignored the unimpressive ride) on my way to Frontierland
Then I left. That's how you do Galaxy's Edge.
