Never mind “will” people respond, the question is ...CAN people respond that quickly?
Picture it. You’re just coming up to the “Thank the Phoenicians” scene in SSE. Your phone vibrates, (because you’re certainly not rude enough to have left the ringer on) and you let it go to voicemail. Ten, twelve minutes later, after NOT getting the Treehouse future again, you disembark and check your voicemail.
Uh oh, Rover is barking, you have to go back to POR. Luckily SSE is right at the front of the park, so it’s only a five or so minute walk over to the bus pick up area. Ten, maybe fifteen minutes later, your bus pulls up ... have to offload or load an ECV or two, and then you can get on the bus yourself.
How long is the bus ride to POR? I dunno, with all the this circular road here and that circular road there, maybe another ten minutes. You’re finally dropped off, hoof it over to your room as quickly as you can, and Rover goes ballistic when he hears you approach the door. Bored barking dog becomes happy, excited, barking dog ... and you’ve been well over the allotted 30 minutes to quiet him down.
And this entire scenario presupposes that you dropped everything you were doing and returned immediately to your resort. Many more people are going to insist on finishing their meal, or waiting until their FP for Frozenstrom, or plain old won’t realize that their phone vibrated whilst under their seat on Soarin’.
