*sigh* Pendantic nitpicky rant incoming and I'm disappointed with myself, especially since me of all people believes in waiting to pass judgement.
I really hope the doors are integrated well and they slide into the wall rather than fold, because that could really ruin the clean look of this portal. For immersion's sake, it should look like a seamless transition as opposed to something that's meant to occasionally be closed. It's like the Warp Pipes entering in Super Nintendo World; they just wouldn't look right with a door in the front.
You can see that white break in the area might be where the door is supposed to fold back, and I'm not sure that will look good in practice. If they have a mouth to the portal, then a small gap, and then the magic that transports you, it's a little meh to me in terms of themeing. I very much prefer the transitions of Galaxy's Edge, Pandora, and Diagon Alley which happen pretty naturally. I'm in no way opposed to doors, especially because I know it requires extra staff to simply use ropes, and if the business model is different here where Celestial Park is open after hours, the massive potential cost savings are massive, but that little touch will be important.
