The design of the thing is beautiful, particularly when complemented by the Costa Daurada weather. But in essence, it's not much more than a gentle, pleasant boat ride past relatively nondescript scenery. There are few notable set pieces along the way and the ride vehicles, though smooth, are so clearly running along a track that any real sense of "adventure" in the journey - exactly the thing that makes Jungle Cruise an unlikely triumph - is lost.
The water guns are also something of a missed opportunity. There's no interaction with the environment here, as you would expect from an attraction with a shooting element - you're left to be content with shooting at the other boats. Fine - except that the opportunities for this are also pretty minimal, particularly when spread across the aforementioned lengthy track. (Even the chance to shoot at guests on the land are surprisingly kept to just once or twice, with the bridges over the track too high to be reached by the low-pressure water cannons.)
Queues were approaching the two-hour mark when I visited. It was admittedly a busy day, but for such a low-energy attraction, I'd be surprised if more than a few guests weren't left somewhat underwhelmed. PortAventura should be applauded for a welcome (and well-funded) addition to their roster of family-level rides, rather than pure kiddie or thrill. But Angkor is torn between attempts at a scenic boat trip and an interactive adventure - and as a result, doesn't quite hit the target on either.
