I hope an opening this summer, because I have to move out aboard...
The park are offering 25% off ling bao and matamba until end of august, so there is no chance of Rookburgh opening before September. And if you read up @CSLKennyNI posted an article which says that the park don't want to open the area as long as social distancing/masks are still a thing.
I'm not really sure why this is the case, as the park isn't exactly selling out everyday, so surely opening rookburgh would be an incentive for people to come and thus sell more tickets. Although, I'm not sure how economically viable it would be to open Charles Lindbergh in the current scenario given ling bao is barely managing to sell rooms and the hotel is having to operate with a stripped back menu and limited opening hours for the bars and restaurants.
I would really love rook burgh to open this year, but in the current situation I wouldn't be surprised if it was 2021 now. An opening in September/November would be nice though, and the area could be heavily marketed through the winter season and draw lots of guests in, but that's only if things are more back to normal by then, which is uncertain.
As long as the park are waiting for social distancing and masks to no longer be a thing, this area is unfortunately not going to open anytime soon. A somewhat naive decision in my opinion, as we could be stuck with the current restrictions for a very long time in the most pessimistic perspective. In which case, this thing is never going to open. Honestly, it would just make more sense to open the area when it's ready, but clearly that's not the current mindset of the park.
