Yeah, exactly. And, if they're on the guidebooks, then there's a good chance that they're first timers or infrequent visitors. The "half-day park!" nonsense comes from the people who have been several times and don't feel like watching the shows or doing any of the non-ride activities. Even with the closures, you've got Star Tours, Lights Motor Action, Indy, Muppet Vision, Great Movie Ride, Aerosmith, Tower of Terror, Beauty & The Beast, Frozen, Toy Story, Voyage of the Little Mermaid, Fantasmic, character meets, and a handful of other entertainment options. To paraphrase what a poster in another thread stated, it's only a half-day park if you ignore a lot of what the park has to offer.
