I have to add my 2 cents. We just returned home. DD 10 has been to Studios before and is a giant Star Wars fan. DD7 did not remember DHS and was excited to go.
*Despite the construction walls, we found the park to be clean and sparkling and the CMs to be great.
*We arrived 30 minutes before opening. We did JTA signup (must for DD10), ST (both girls loved it, should've gone again), shopping for light sabers, Dino Gerties ice cream, JOTLM, Frozen singalong (delightful!), Launch Bay (props, Jawa trading, shopping) and Streetmosphere before breaking for a late 1:30pm lunch. Returned at 5:30pm for Backlot Express dinner, JTA show (Darth Vader and 7th Sister), Launch Bay (2 character meets - Chewbacca and Kylo Ren), SITS fireworks at 9:30.
*We did not have an interest in any of the closing soon attractions on Streets of America and didn't miss them.
*We still missed Mickey and other character meets, ToT, RnR, BatB, Disney Jr, Muppets, GMR, TSMM, One Man's Dream and Indy. Also skipped the SW movies. Would've loved to sit down for a great themed dinner at Sci Fi or 50s PTC. We also skipped Fantasmic.
My conclusions - if you are not a frequent visitor I think that this park has a lot to offer with good variety and is still a full day experience. We are slow movers and I felt like we missed a lot. With our break time we could have added in probably 3 more attractions and a TS meal. I think WDW is going to great lengths to keep the park relevant and step up the offerings while constructions is ongoing. There is a new stage show, Capt Phasma procession, and nighttime SW spectacular (new fireworks) coming hopefully by June. Any SW fan will have a great day. For everyone else, there is plenty to do.
IMHO, this park is totally worth adding a day to a multi-day ticket, if not making a special trip for the SW offerings alone.
