Well, I know there was certainly never random spots of standing water when I went running on Deck 4 on the Fantasy 2 weeks ago, so yeah I'm completely willing to just go running down some stairs. Who needs their tibia and fibula to be unbroken, anyway. Overrated bones IMO.
Every time I went running, it was in the 7am hour so Senses wouldn't be open, but that "path" for running is worthless. I'm sure Disney's engineeers did the math and figured out that there aren't enough runners to merit an uninterrupted loop versus whatever advantages this new setup entails, but it pretty clearly eliminates the Wish from consideration for me (and the new ships if/when they have this same configuration). I don't do treadmill running, thanks, and certainly not on "vacation," and running is extremely important to me. I don't blame Disney for the cost/benefit analysis, but that's the "cost" in that scenario. YMMV.
