We went for the first time this year. We loved it! I am not a Star Wars fan but DH and my two boys are. But I have to say, that is one of the most memorible days of our trip. I had no clue who half the characters were but it was so much fun. So my tips would be:
1) Get there early. We arrived at the turnstyles 90 minutes before the park opened. We were not the first ones there. We were probably about 7 families back from the turnstyle. It worked out because we were able to see the preshow on top of the front gates. If you were first, you would miss it. However, the first ones moved back and nobody took their spot.
2) Only plan on SWW stuff. Other than TSM, we did not visit any attraction other than SWW.
3) Get a spot for the parade early. I saved us a spot while DH took the kids for meet and greets. I believe the parade was at 11:20 or 11:40. I found a spot at 10:00. It does get hot, not much shade to wait in. That was the hard part but worth it.
We did not see any of the special events like the actors from the movies, the question and answer show, nor did we stay for the Hoopla at the end of the day. These were all real crowded and the boys did not want to wait. All in all, we had a great time and are already booked for next year.
