First post here. I'm living in Hong Kong which means I get to venture to theme parks over this side of the globe. Just like to point out that the climate in Singapore is much more extreme than Florida - consistently around the 30c mark, humidity is always 90%+, and there's a guaranteed rainstorm practically every day of the year.
That said, the JPRA at Universal Singapore has none of these technical issues, at least not in my experience. Although, this version of the ride is newer than the Orlando one... so they perhaps designed a new approach to creating the scenes to circumvent issues (iirc, fewer of the dinos are actually in-water).
That said, the version of the ride in Orlando, imo, is a far better experience. The vehicle in Singapore is one of them free-floating circular contraptions... which means that you only get to see a small percentage of the dinosaurs, as your back is to the rest.
The t-rex is anti-climatic, too. In this version it comes from high up. Yet, 90% of the people on the vehicle seem to miss it, because they just don't know where to look.
At least in Orlando, everybody gets to see the one-armed t-rex.
