If I’m understanding walkability correctly, that’s not a great comparison. From Cabana I can briskly walk 15 minutes along a garden/waterway path to be front of the line at park open.
To my understanding, the 3 Epic hotels are too far for walking.
I’d still want to stay at Helios or the other one that’s on the Epic side of the highway, but would only do a 1-night stay before transferring to a different hotel.
