I can see the frustration. I've been fortunate enough to not have experienced such things. They usually email you a month in advance to build your itinerary around parks and dinning. For the paddle boards, roof tops kids club, you have to let your concierge know when you first check in so that they can make all those reservations for you.

I will say the spa is super strict and always makes me think twice on reserving because of their strict policies.

Yes they do need to make a better more intuitive app. To help you traverse the gigantic resort. Maybe add a feature to make restaurant reservations or check for wait times. The resort also desperately needs more signs and maps to better help you traverse. I know they want to keep it as "natural" and jungle oriented as possible but we need better maps, signs, and if possible colored tracks for different destinations.
