All the water ride talk got me thinking about something. The one thing that sucks at Islands of Adventure and Orlando in general is when it storms most out door rides close down...in IOA that is around 9 rides, 3 play areas, and 1 meet and greet out of commission until the storm passes. Mine you IOA has a total of 19 attractions (minus mystic fountain, frog choir, Oh, The Stories You'll Hear and the triward show) 20 if you include Kong when it opens but when it storms you lose 14 of those attractions heck when it rains most people don't want to go and experience those 11 of those attractions. Usually 15 minutes to an hour is how long the storms last but some days you have 3-5 hours of rain meaning people are going to leave.
I wonder if Universal plans to remedy this by creating an half indoor, half outdoor theme park but not in the traditional sense of oh we are inside now we are outside but kinda a large scale knockturn alley in Diagon where the connections are seamless. This would let them be able to create full themed environments but give them additional controls as well. It could always be night, always be day, essentially weather proof (good for AAs), everything would be in the hands of UC and OPs for even more impressive landscapes.
