I think they look lovely, and I like that they've developed to have more "individual" personalities than the initial concept art suggested. We're tentatively booked at Stella Nova for August 2025, for the last 2 nights of a 6-night stay that will start at Royal Pacific. While I'd love to stay at the Helios Grand instead, I suspect that the price point may be too high for us when it becomes available.
What I'm curious to know is whether the sidewalks leading from Terra Nova and Stella Luna toward Epic Universe will provide a viable walking path to the park -- presumably with a tunnel under, or pedestrian bridge over, the highway. (Granted, early indications are not favorable, with a "shuttle to the parks" being the only advertised transportation amenity.) If you could walk to Epic from there, it would be a huge selling point. Not that a short bus ride would be terrible, either...
