Once you have entered the park through the main entrance your face has been recognised, this was explained to us the other night.
So you can go into Helios for a drink or a meal and then go back through the guest entrance back into the park, you just can’t go through that way first if you’re not a hotel guest.
We’re doing that today at some point from the park, but we will be entering first through the main park entrance.
Hope that makes sense
