Helios built the plaza for this reason. Guests will be able to be in the park for EPIC. For those of the 500 rooms that are going to Epic early admission that day they will be into that plaza prior to 8am.Also on this comment. Helios is early entry like the other hotels.. People line up long before the gates open. Transportation is going to be running early to enable those guests to reach the park to do so. Where is this head start you are expecting? At most I expect you'll have the advantage of less crowds so you won't have to get up AS early.. but you're not really going to have any advantage in the park unless they let your gate go early.
I expect to deal with the crowds they will have to do some sort of rope drop inside the park.. Can't have hundreds of hotel room guests crowding in the lobby waiting for the opening time.
And isn't early access only to Super Mario Land and the racers attraction?
It is an advantage and more than the other resorts because it is a Fifteen min bus ride that starts prior to 8, but Cabana Bay, HRH, Porto, Aventura, Dockside, saphire...have far more guests than can all make it on the first buses provided even with preparing for demand.
That bus procedure even with the road ramps is going to take more time than Helios guests entering. And then sharing the experience together at those main gates will take even with optimum staffing.
We can't dimisnh the obvious advantage Helios has there by design of bej g right at Celestial Park, even if one does not see it as a value for them personally.
